It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when this verse was revealed: "The example of those who spend their wealth in the way of Allah is like that of a grain which grows seven ears, in every ear a hundred grains", the Messenger of Allah (peace and blessings be upon him) supplicated: "O my Lord, give my Ummah even more." Then this verse was revealed: "Who is it that will lend Allah a goodly loan so that He may multiply it for him many times over?" He (peace and blessings be upon him) again said: "O my Lord, give my Ummah even more." Then this verse was revealed: "Only the patient will be given their reward in full, without measure."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Nafi' except Isa bin al-Musayyab, and no one from Isa except Abu Isma'il al-Mu'addib; Hafs bin Umar al-Duri is alone in narrating it."
