The author mentions the praying person who sleeps and speaks; does the sleeper’s wudu’ (ablution) not become invalid?

Question : O Shaykh, and if he sleeps and speaks? He sleeps, O Shaykh, the wudu’ is not accepted.

Answer : No, if the sleep is light. Sometimes some people are overcome by sleep during the day, and, praise be to Allah, they speak. And some people, may Allah not make us and you like that, speak about what they did that day. May Allah accept.
