Hadith 6149
Usama b. Zaid told that the Prophet used to take al-Hasan and him and say, "0 God, I beseech Thee to love them, for I love them." In a version he told that God's messenger used to take him and put him on his knee, then put al-Hasan on the other knee, and after embracing them say, "0 God, I beseech Thee to have compassion on them, for I have compassion on them." Bukhari transmitted it.
وَعَنْ أُسَامَةَ بْنِ زَيْدٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ يَأْخُذُهُ وَالْحَسَنَ فَيَقُولُ: «اللَّهُمَّ أَحِبَّهُمَا فَإِنِّي أُحبُّهما» وَفِي رِوَايَةٍ: قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَأْخُذُنِي فَيُقْعِدُنِي عَلَى فَخِذِهِ وَيُقْعِدُ الْحَسَنَ بْنَ عَلِيٍّ عَلَى فَخِذِهِ الْأُخْرَى ثُمَّ يَضُمُّهُمَا ثُمَّ يَقُولُ: «اللَّهُمَّ ارْحَمْهُمَا فَإِنِّي أرحمُهما» . رَوَاهُ البُخَارِيّ
