The Prophet (PBUH) said: "There is no Muslim who supplicates to Allah with a dua that does not contain sin or severing of kinship ties, but Allah will give him one of three things: either He will answer his prayer quickly, or He will store it for him in the Hereafter, or He will divert an equivalent evil away from him."

The Prophet (PBUH) said: "There is no one who is afflicted with distress or grief and says: Allahumma inni abduka, ibnu abdika, ibnu amatika, nasiyati biyadika, madin fiyya hukmuka, adlun fiyya qada'uka... except that Allah will take away his distress and grief and replace it with joy."
