Sayyidah Asma' bint Yazid (may Allah be pleased with her) narrates that when Sayyiduna Ibrahim (may Allah be pleased with him), the son of the Messenger of Allah (peace and blessings be upon him), died, the Messenger of Allah (peace and blessings be upon him) wept. Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: "You are the one who knows Allah's right best of all (and yet you are weeping)." So he (peace and blessings be upon him) said: "The eye sheds tears and the heart grieves, but we do not say what displeases the Lord; and O Ibrahim, we are indeed grieved at your parting."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibn Khuthaym except Muslim bin Khalid."
