(Those who spent and fought before the victory are not upon a level (with the rest of you)…) [57:10]. Muhammad ibn Fudayl reported that al-Kalbi related that this verse was revealed about Abu Bakr al-Siddiq, may Allah be well pleased with him. This is evidenced by the report which was related to us from Muhammad ibn Ibrahim ibn Muhammad ibn 'Abdihi ibn Yahya> Abu'l-Hasan Muhammad ibn 'Abd Allah al-Saliti> 'Uthman ibn Sulayman al-Baghdadi> Ya'qub ibn Ibrahim al-Makhzumi> 'Amr ibn Hafs al-Shaybani> al-'Ala' ibn 'Amr> Abu Ishaq al-Fazari> Sufyan al-Thawri> Adam ibn 'Ali> Ibn 'Umar who said: “As the Prophet, Allah bless him and give him peace, was sitting with Abu Bakr al-Siddiq, who was wearing a cloak which he gathered round his chest with pins, Gabriel, peace be upon him, came down, conveyed Allah's greetings of peace to him and said: 'O Muhammad, why is Abu Bakr wearing a cloak which he gathers round his chest with pins?' He said: 'O Gabriel, he has spent all his wealth before the conquest [of Mecca]!' He said: 'In that case, convey to him Allah's greetings of peace, glorified and exalted is He, and tell him that your Lord asks you: are you pleased with Me in your state of poverty or are you indignant?' The Prophet, Allah bless him and give him peace, addressed Abu Bakr: 'O Abu Bakr, Gabriel is here to convey the greetings of peace of Allah, glorified and exalted is He, and He is asking you: are you pleased with Him in your state of poverty or are you indignant?' Upon hearing this, Abu Bakr wept and said: 'How can I be indignant with my Lord? I am pleased with my Lord! I am pleased with my Lord!' ”
