Ibn Abbas said: To raise the voice for making the mention of Allah after the people had finished their obligatory prayer was for in vogue the time of the Messenger of Allah ﷺ. Ibn Abbas said: I used to know by it when they finished the prayer and would listen to it (making the mention of Allah).

Narrated Ibn Abbas: said When the Messenger of Allah ﷺ sent Muadh to Yemen, he said to him You are going to a people who are people of the book. So call them to bear witness that there is no diety but Allah, and that I am the Messenger of Allah. If they obey you in this respect, tell them that Allah has prescribed five prayers on them every day and night. If they obey you in this regard tell them that Allah has prescribed sadaqah (zakat) on their property and returned it to their poor. If they obey you in this respect, do not take the best of their property. Beware of the curse of the oppressed, for there is no curtain between it and Allah.
