"By the One in Whose hand is my soul, if one of you were to take a rope and gather firewood on his back that would be better for him than coming to a man to whom Allah, the Mighty and Sublime, has given of His bounty and asking him (for help). Which he may or may not give. (Using translation from Nasāʾī 2589)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «وَالَّذِي نَفْسِي بِيَدِهِ لَأَنْ يَأْخُذَ أَحَدُكُمْ حَبْلَهُ فَيَحْتَطِبَ عَلَى ظَهْرِهِ خَيْرٌ لَهُ مِنْ أَنْ يَأْتِيَ رَجُلًا أَعْطَاهُ اللهُ مِنْ فَضْلِهِ فَيَسْأَلَهُ أَعْطَاهُ أَوْ مَنَعَهُ»
