Hadith 6165
Usama b. Zaid said: I went to the Prophet one night about something I required and he came out with something (I did not know what) under his cloak. When I had finished telling him my business, I asked him what he had under his cloak, and when he opened it, I saw al-Hasan and al-Husain on his hips. He then said, "These are my sons and my daughter's sons. 0 God, I love them, so I beseech Thee to love them and those who love them." Tirmidhi transmitted it.
وَعَن أسامةَ بنِ زيدٍ قَالَ: طَرَقْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ لَيْلَةٍ فِي بَعْضِ الْحَاجَةِ فَخَرَجَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ مُشْتَمِلٌ عَلَى شَيْء وَلَا أَدْرِي مَا هُوَ فَلَمَّا فَرَغْتُ مِنْ حَاجَتِي قُلْتُ: مَا هَذَا الَّذِي أَنْتَ مُشْتَمِلٌ عَلَيْهِ؟ فَكَشَفَهُ فَإِذَا الْحَسَنُ وَالْحُسَيْنُ عَلَى وَرِكَيْهِ. فَقَالَ: «هَذَانِ ابْنَايَ وَابْنَا ابْنَتِي اللَّهُمَّ إِنِّي أُحِبُّهُمَا فأحبهما وَأحب من يحبهما» رَوَاهُ التِّرْمِذِيّ
