I thought I would post an extract from the ‘Umdah al-Riayah’ for the benefit of readers.
In the ‘Sharh al-Wiqayah’ it is written:
[And the loud laughter of a person praying, mature, bowing and prostrating] such that the wudu of a child is not invalidated by loud laughter. Its condition is: That it be in a prayer containing bowing and prostration, such that if he were to laugh aloud in the funeral prayer, or prostration of recitation it does not invalidate wudu. Rather it only invalidates that which they laughed aloud in. The conditions which have been mentioned are because the invalidating of wudu by it (loud laughter) is established from the hadith.
Shaykh Abd al-Hayy al-Luknawi commented on this in his ‘Umdah al-Riayah’ (1/338):
“It is that which is related by al-Tabarani from Abu Musa al-Ashari (Allah be pleased with him): ‘The Messenger of Allah (Allah bless him and give him peace) was praying with the people when a man entered and fell into a hole which was in the masjid, and there were problems with his eyesight. Many of the people laughed and they were in the prayer, so the Messenger of Allah (Allah bless him and give him peace) ordered those who laughed to repeat the wudu and prayer.’ Likewise it was reported by al-Darqutni, Abd al-Razzaq, Abu Dawud in his ‘Marasil’, Ibn Abi Shaibah and others.
The hadith has supporting narrations related by al-Darqutni, Ibn Adiyy and other than them both, as was detailed by al-Zaylai in ‘Takhrij Ahadith al-Hidayah’. And I have a detailed discussion for and against them, the subsidiary points of the issue and those that are related to it in a treatise which I named ‘Al-Has-hasah bi Naqd al-Wudu bil-Qahqahah’…”
Dr Salah Abul Hajj in his notes at the bottom of the same page referenced the hadith and added some additional comments as follows:
Sunan al-Darqutni (1:167) al-Kamil (3:167) Tarikh Jurjan (1:405) Sunan al-Bayhaqi al-Kabir (2:252) Musannaf Abd al-Razzaq (2:376) Musannaf Ibn Abi Shaibah (1:341) Marasil Abi Dawud (p.75) Al-Luknawi said after citing the chains of transmission for the hadiths regarding loud laughter in ‘Al-Has-hasah bi-Naqd al-Wudu bil-Qahqahah’: “These musnad narrations, and mursal reports are clear evidence of the invalidating of wudu by laughing aloud”. And whoever seeks more detail regarding the hadith narrations regarding the invalidating of wudu by laughing aloud then let him refer to ‘Ilaa al-Sunan’ (1/132-144).
