1038 - Muhammad ibn al-Wazir narrated to us, saying: Marwan ibn Muhammad narrated to us, saying: Ibn 'Ayyash narrated to us, saying: Abd al-Aziz ibn Ubaydullah narrated to me, from Nafi', from Ibn Umar, who said: "Whoever guffaws (laughs aloud), let him repeat the wudu and the prayer. And whoever smiles, there is no wudu upon him, nor does it break his prayer."
1039 - 'Amr ibn 'Uthman narrated to us, saying: Al-Walid ibn Muslim narrated to us, saying: Abu 'Amr al-Awza'i said—concerning one who smiles during his prayer—: "He proceeds with his prayer. But if he laughs with a guffaw, he repeats the wudu and the prayer."
1040 - Muhammad ibn al-Wazir narrated to us, saying: Marwan narrated to us, saying: Malik said: "There is no wudu upon him."
Chapter: One Who Smiles During His Prayer
• I heard Ishaq say: "If a man speaks after he has performed a rak'ah or two, he restarts the prayer and does not repeat the wudu. And if he smiles and does not guffaw, he proceeds with his prayer, unless he guffaws."
1041 - Ishaq narrated to us, saying: 'Ali ibn Thabit informed us, saying: Al-Wazi' ibn Nafi' al-'Uqayli informed us, from Abu Salamah ibn 'Abd al-Rahman, from Jabir ibn 'Abdullah—may Allah be pleased with them both—(1), that the Messenger of Allah (peace be upon him) prayed 'Asr, and he smiled during his prayer, so he said: "I saw Jibril, and he smiled at me, so I smiled at him."
(1) Thus it is in the original. Perhaps he assumed it to be: Jabir ibn 'Abdullah ibn 'Amr ibn Haram al-Ansari, the well-known companion. However, it is in this hadith—as has been explicitly stated in its chains of transmission—: Jabir ibn 'Abdullah ibn Ri'ab.
