Ameer al-Momineen (a.s) said: “Pious people can be recognized through the following signs: honesty in speech, trustworthiness, keeping their promises, minimal jealousy and sorrow, associating with relatives, being kind with the weak ones, minimal sexual intercourse with women, doing good deeds, having a good temper, having patience, and putting to use the knowledge that aids them to get nearer to God: “For those who believe and work righteousness, is (every) blessedness, and a beautiful place of (final) return.” [The Holy Quran: Ra'd 13:29] “Tooba” is the name of a Heavenly tree which is rooted in the Prophet's (a.s) house. There are branches of this tree in the homes of the believers. These branches will yield whatever you desire. The branches are so extensive that if someone races under them with a fast riding horse for even one hundred years, he will not leave the shade of this branch. If a crow starts from the base of the tree and tries to fly towards the top, it can never reach there until it gets old. So beware, and try to attain this boundless blessing. Indeed a believer is busy doing his work, and the people are safe from him. When the night comes, he will fall prostrate in God's worship. He will ask God who has created him to save him from the Fire of Hell. So beware and try to be this way.”
