The Messenger of Allah (s) advised `Ali b. Abi Talib (as), saying: O `Ali! When the bride enters your house, then take off her footwear when she sits, and wash her feet. Sprinkle the water from the door of your house to the furthest part of your house, for if you do that, Allah will remove seventy types of poverty from your house, and put seventy types of blessings therein, and send down seventy mercies that flutter on the head of the bride, until all her blessings are placed in every corner of your house. It will protect the bride from being afflicted with insanity and leprosy as long as she resides in that house. During her [menstrual] week, prevent her from [consuming] milk, vinegar, coriander, and sour apple – these four things. So, `Ali (as) said: O Messenger of Allah! For what reason should I prevent her from these four things? He said: Because the womb becomes sterile and cold from these four things; and a mattress at the end of the house is better than a sterile woman. So, `Ali (as) said: O Messenger of Allah! Why would vinegar be prevented? He said: When she menstruates upon [eating] vinegar, she will never become fully purified. Coriander moves the menstrual blood in her stomach (or insides) and intensifies childbirth for her. Sour apple cuts her menstruation short, which will ail her. Then, he said: O `Ali! Do not have intercourse with your woman at the beginning of a month, in its middle, or at its end, or else insanity, leprosy, and dementia will hasten to her and her child. O `Ali! Do not have intercourse with your woman after Dhuhr, for if you are apportioned with a child in that time, it will have a deformed eye, and Satan becomes happy with deformity in humanity. O `Ali! Do not speak during intercourse, for if you are apportioned with a child at that time, he will not be protected from muteness. None of you should look at the private of his woman; lower your gaze during intercourse, for looking at the private bequeaths blindness in the child. O `Ali! Do not have intercourse with your woman while lusting after a wife of someone else, for I fear that, if you are apportioned with a child in that time, it will be effeminate (mukhannath), feminine, and disgraceful. O `Ali! He who is sexually impure in a bed with his woman should not recite the Quran, for I fear that a fire will descend upon them from the sky and burn them. O `Ali! Do not have intercourse with your woman except that you have a covering and that your wife has a covering. Do not have intercourse under a single covering, or the desire will fall, and that will bequeath enmity between you, and that will lead you to separation and divorce. O `Ali! Do not have intercourse with your woman while standing, for that is from the actions of donkeys; and if you are apportioned with a child in that time, it will urinate in the bed just as donkeys urinate in all places. O `Ali! Do not have intercourse with your woman on the eve of [Eid] al-Fitr, for if you are apportioned with a child in that time, that child will be of much evil. O `Ali! Do not have intercourse with your woman on the eve of [Eid] al-Adha, for if you are apportioned with a child in that time, it will have six fingers or four fingers. O `Ali! Do not have intercourse with your woman under a fruitful tree, for if you are apportioned with a child in that time, it will be an executioner, a killer, or a military man. O `Ali! Do not have intercourse with your wife in the sunshine without a barrier that covers both of you, for if you are apportioned with a child in that time, it will remain in poverty until it dies. O `Ali! Do not have intercourse between the adhan and the iqama, for if you are apportioned with a child in that time, it will be too afraid to shed blood [in the battlefield]. O `Ali! When you woman becomes pregnant, do not have intercourse with her unless you are upon ablution, otherwise if you are apportioned with a child, it will be blind of heart and stingy of hands. O `Ali! Do not have intercourse with your wife in the middle of Sha`ban, for if you are apportioned with a child, it will have a blemish on its face. O `Ali! Do not have intercourse with your wife at its end – when two days remain of it – for if you are apportioned with a child, it will be a tax collector or a supporter of a tyrant; and the destruction of a people will be on its hands. O `Ali! Do not have intercourse with your wife on the roofs of buildings, for if you are apportioned with a child, it will be a hypocrite, a charlatan, and an innovator. O `Ali! When you are going out on a journey, do not have intercourse with your wife on that night, for if you are apportioned with a child, it will be one who spends his money unjustly – and the Messenger (s) recited, “Surely, the wasteful are the brethren of the devils.” (17:27) O `Ali! Do not have intercourse with your wife in the day or the night of a three-day journey, for if you are apportioned with a child, it will be a supporter of all who oppress you. O `Ali! Betake to having intercourse on the eve of Monday, for if you are apportioned with a child, it will be one who memorized the Book of Allah and is pleased with what Allah has given him. O `Ali! If you have intercourse with your wife on the eve of Tuesday, and you are apportioned with a child, he will be granted martyrdom after bearing witness that there is no god but Allah and that Muhammadan is the Messenger of Allah; and Allah will not punish it with the pagans, it will have a sweet mouth, a merciful heart, a generous hand, an a tongue that is purified of backbiting, lying, and false accusations. O `Ali! If you have intercourse with your wife on the eve of Thursday and you are apportioned with a child, it will be a ruler or a scholar. If you have intercourse with her on Thursday after the Sun reaches its zenith in the sky and you are apportioned with a child, Satan will not approach him until he greys and understands, and Allah will grant him peace in the religion and in this world. O `Ali! If you have intercourse with her on the eve of Friday, and a child is born to you, it will be a preacher and speaker. If you have intercourse with her on Friday after `Asr, and a child is apportioned for you, it will be recognized, prominent, and knowledgeable. If you have intercourse with her on the eve of Friday after the final `Isha’, then it is hopeful that you will have a child from the Abdal, God-willingly. O `Ali! Do not have intercourse with your wife in the first hour of the night, for if you are apportioned with a child, there is no protection from it becoming a sorcerer preferring this world over the Hereafter. O `Ali! Preserve this advice of mine, just as I have preserved it on behalf of Gabriel (s).
