Discussion of the hadith of A'ishah, in which the Messenger of Allah (peace and blessings be upon him) would kiss some of his wives and then pray without performing wudu; it is a valid hadith by the totality of its chains, although al-Bayhaqi

The Shaykh : And of this type is the hadith of A'ishah (may Allah be pleased with her) which is a valid hadith by the totality of its chains, even though al-Bayhaqi (may Allah have mercy on him) weakens this hadith. He says that the hadith is weak from all of its chains. But, glory be to Allah, where is he from the rule that a weak hadith is strengthened by the multiplicity of its chains? Why is that? Because it contradicts his school of jurisprudence, even though he has great merit in collecting the Sunnah and serving the books of Imam al-Shafi'i, as is well known.
