56/76. Chapter:
The help of poor and pious men in war
وَقَالَ ابْنُ عَبَّاسٍ أَخْبَرَنِي أَبُو سُفْيَانَ قَالَ لِي قَيْصَرُ سَأَلْتُكَ أَشْرَافُ النَّاسِ اتَّبَعُوهُ أَمْ ضُعَفَاؤُهُمْ فَزَعَمْتَ ضُعَفَاؤُهُمْ وَهُمْ أَتْبَاعُ الرُّسُلِ.Narrated Ibn 'Abbas رضي الله عنهما: Abu-Sufyan said to me, "Caesar said to me, 'I asked you whether the wealthy people followed him (i.e., Muhammad ﷺ) or the poor, and you said that the poor. Really, such are the followers of the Messengers.'"
Sahih Bukhari
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، حَدَّثَنَا مُحَمَّدُ بْنُ طَلْحَةَ، عَنْ طَلْحَةَ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، قَالَ رَأَى سَعْدٌ ـ رضى الله عنه ـ أَنَّ لَهُ فَضْلاً عَلَى مَنْ دُونَهُ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم " هَلْ تُنْصَرُونَ وَتُرْزَقُونَ إِلاَّ بِضُعَفَائِكُمْ ".
Narrated Mus`ab bin Sa`d: Once Sa`d (bin Abi Waqqas) thought that he was superior to those who were below him in rank. On that the Prophet (ﷺ) said, "You gain no victory or livelihood except through (the blessings and invocations of) the poor amongst you."
