Answered Du'a/Supplications.

[Abu Hafsat]

As-Salaam alaikum, 

It has been related by al-Tabaraani on the authority of Ibn Abbas, may Allah be pleased with him, who said that the Messenger of Allah, Sallallahu alaihi Wasallam, said :

"Five are among the the supplications which are answered." He then mentioned them : "The supplication of a Muslim for his fellow brother who is absent, that of the just Imam, the supplication of the oppressed, the supplication of the traveller and a man who supplicates for his two parents".
