4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Mahbub from Malik ibn ‘Atiyyah from Durays al-Kunasi from abu Ja’far عليه السلام who has said the following: “The Messenger of Allah once was passing by a man who was planting a plant in his yard. The Holy Prophet stopped and asked, ‘Should I tell you about a plantation that has stronger roots, ripens faster and is of finer fruits?’ The man said, ‘Yes, O Messenger of Allah, tell me about it.’ The Messenger of Allah said, ‘In the morning and evenings say, “Glory belongs to Allah, all praise belongs to Allah, no one deserves to be worshipped except Allah and Allah is greater than can be described.” If you say this, for each time you will have ten trees in paradise of different kinds of fruits. They are (the reward) from perpetually charitable trusts.’ The Imam said that the man then said, ‘I take Allah as witness that my yard is a charitable trust and the needy Muslims are its beneficiaries.’ Allah, the Most Majestic, the Most Holy, then revealed the verses of the Holy Quran: ‘For those who spend for the cause of Allah, observe piety, (92:5) and believe in receiving rewards from Allah, (92:6) We shall facilitate the path to bliss’” (92:7)
