باب التَّبَسُّمِ وَالضَّحِكِ
Sahih al-Bukhari 6088

Narrated Anas bin Malik:

While I was going along with Allah's Messenger (ﷺ) who was wearing a Najrani Burd (sheet) with a thick border, a bedouin overtook the Prophet (ﷺ) and pulled his Rida' (sheet) forcibly. I looked at the side of the shoulder of the Prophet (ﷺ) and noticed that the edge of the Rida' had left a mark on it because of the violence of his pull. The bedouin said, "O Muhammad! Order for me some of Allah's property which you have." The Prophet (ﷺ) turned towards him, (smiled) and ordered that he be given something.

حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ الأُوَيْسِيُّ، حَدَّثَنَا مَالِكٌ، عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنْتُ أَمْشِي مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَعَلَيْهِ بُرْدٌ نَجْرَانِيٌّ غَلِيظُ الْحَاشِيَةِ، فَأَدْرَكَهُ أَعْرَابِيٌّ فَجَبَذَ بِرِدَائِهِ جَبْذَةً شَدِيدَةً ـ قَالَ أَنَسٌ فَنَظَرْتُ إِلَى صَفْحَةِ عَاتِقِ النَّبِيِّ صلى الله عليه وسلم وَقَدْ أَثَّرَتْ بِهَا حَاشِيَةُ الرِّدَاءِ مِنْ شِدَّةِ جَبْذَتِهِ ـ ثُمَّ قَالَ يَا مُحَمَّدُ مُرْ لِي مِنْ مَالِ اللَّهِ الَّذِي عِنْدَكَ‏.‏ فَالْتَفَتَ إِلَيْهِ فَضَحِكَ، ثُمَّ أَمَرَ لَهُ بِعَطَاءٍ‏.‏
