Three; Ash-Shafi’i said, if there are two letters that come out when someone holds his small cough and both can be understood, then it can damage prayer (salat). But if two letters cannot be understood, then it cannot cancel the prayer (salat).
That is a brief explanation of holding small cough during prayer (salat). Do you have questions? The problem is simple and the explanation is very clear. So, I hope you understand. But if you want to ask, please ask!
I think that is enough for this article. May be useful! Amen!
See you again in the next article!
The explanation above I found in, Hasan Sulaiman an-Nuri and ‘Alawi Abbas al-Maliki, Ibaanatu al-Ahkaam Syarhu Buluughi al-Maraam, Dar al-Fikr, Beirut, Vol. I, p.239.
