If anyone asks you refuge for Allah’s sake give him refuge; and if anyone asks you (for something) for Allah’s sake, give him. Sahl and Sulaiman said: if anyone calls you, respond to him. The Agreed version goes; if you do not afford to compensate him, pray Allah for him until you know that you have compensated him.
قَالَ رَسُولُ اللَّهِ ﷺ مَنِ اسْتَعَاذَكُمْ بِاللَّهِ فَأَعِيذُوهُ وَمَنْ سَأَلَكُمْ بِاللَّهِ فَأَعْطُوهُ وَقَالَ سَهْلٌ وَعُثْمَانُ وَمَنْ دَعَاكُمْ فَأَجِيبُوهُ ثُمَّ اتَّفَقُوا وَمَنْ آتَى إِلَيْكُمْ مَعْرُوفًا فَكَافِئُوهُ قَالَ مُسَدَّدٌ وَعُثْمَانُ فَإِنْ لَمْ تَجِدُوا فَادْعُوا اللَّهَ لَهُ حَتَّى تَعْلَمُوا أَنْ قَدْ كَافَأْتُمُوهُ
