Al-Adab Al-Mufrad, Book 14, Hadith 278 (In-Book) ⓘ

Anas ibn Malik said, "The Prophet, may Allah bless him and grant him peace, was merciful. No one came to him but that he promised himself something and carried out that promise if he had anything to give. The iqama for the prayer had been given when a bedouin came and took hold of his garment and stated, 'I am still not satisfied.' The Bedouin alarmed the Prophet's wives. The Prophet went with him until the man had received what he wanted. Then he returned and prayed."

حَدَّثَنَا ابْنُ أَبِي الاسْوَدِ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، قَالَ‏:‏ حَدَّثَنَا سَحَّامَةُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ الأَصَمِّ قَالَ‏:‏ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ‏:‏ كَانَ النَّبِيُّ صلى الله عليه وسلم رَحِيمًا، وَكَانَ لاَ يَأْتِيهِ أَحَدٌ إِلاَّ وَعَدَهُ، وَأَنْجَزَ لَهُ إِنْ كَانَ عِنْدَهُ، وَأُقِيمَتِ الصَّلاَةُ، وَجَاءَهُ أَعْرَابِيٌّ فَأَخَذَ بِثَوْبِهِ فَقَالَ‏:‏ إِنَّمَا بَقِيَ مِنْ حَاجَتِي يَسِيرَةٌ، وَأَخَافُ أَنْسَاهَا، فَقَامَ مَعَهُ حَتَّى فَرَغَ مِنْ حَاجَتِهِ، ثُمَّ أَقْبَلَ فَصَلَّى‏.‏
