Abdullah bin Abbas (R.A) says that the Messenger of Allah said,'Five person's supplication shall be accepted - 1. An oppressed person's until he is compensated. 2. A Haji's supplication until he returns home. 3. A Mujahid's supplication(Muslim warrior in defence of faith)until he accomplishes his Jihad. 4. An ailing person's supplication until he becomes healthy 5.And a Muslim's supplication for another Muslim in his absence." The Messenger of Allah said,"Out of all these supplications,the supplication of a Muslim for another in his absence is accepted promptly.(Baihaqi) #supplication
