The hadith reads:
عن عبد الرحمن بن عوف، رضي الله عنه قال: أخذ النبي صلى الله عليه وسلم بيدي فانطلقت معه إلى إبراهيم ابنه وهو يجود بنفسه، فأخذه النبي صلى الله عليه وسلم في حجره حتى خرجت نفسه قال: فوضعه وبكى قال: فقلت: تبكي يا رسول الله وأنت تنهى عن البكاء
قال: إني لم أنه عن البكاء ولكني نهيت عن صوتين أحمقين فاجرين، صوت عند نغمة لهو ولعب ومزامير الشيطان، وصوت عند مصيبة لطم وجوه وشق جيوب، وهذه رحمة ومن لا يرحم لا يرحم
The Prophet (upon whom be peace and blessings) took the hand of the companion, Abdur Rahmaan bin 'Owf, and they proceeded to visit the Prophet's ailing son, Ibraheem. They found the infant in the throes of death, so the Prophet took him to his breast and held him until his spirit left him. Then he put the child down and wept, whereupon Abdur-Rahmaan asked in astonishment, "You are weeping, Oh Messenger of Allah, while you prohibit crying!?" The following is the Prophet's reply:
"Verily, I did not prohibit weeping but rather, I forbade two voices which are imbecilic and sinfully shameless: one, a voice to the accompaniment of musical amusement and Satan's instruments; the other, a voice due to some calamity, accompanied by striking of the face and tearing of garments. But this stems from compassion, and whosoever does not show compassion will not receive it."
(Al-Mustadrak 'alas Saheehayn, Sunan Al-Baayaqhi Alkabri, Sharah Ma-ani Al-Athar, Musannif Ibn Abi Sheba)
One source says that it is "hasan" whereas another says that it is "daif". Is there any evidence for these gradings?
