“The Messenger of Allah has said, ‘Jibril spoke to me that Allah, the Most Majestic, the Most Holy, sent an angel to earth and the angel began walking until he came to a door where a man was asking for permission from the people of the house. The angel asked him, ‘What do you need from the owner of this house?’ He replied, ‘He is a Muslim brother (in belief). I have come to visit him for the sake of Allah, the Most Blessed, the Most High.’ The angel then asked, ‘Is that the only reason for your visit?’ The man said, ‘Nothing else has brought me here but that.’ The angel then said, ‘I am the Messenger of Allah to you and He sends you the greeting of peace and says, ‘I have made paradise obligatory for you.’ The angel then said, ‘Allah, the Most Majestic, the Most Holy, says, ‘Whoever of the Muslims visits an other Muslim, in fact, has not visited him but he has visited Me and his reward from Me is paradise.’”
