Hadith 679
خمس دعوات يستجاب لهن : دعوة المظلوم حتى ينتصر ودعوة الحاج حتى يصدر و دعوة المجاهد حتى يقعد ”ودعوة المريض حتى يبرأ“ ودعوة الأخ لأخيه بظهر الغيب ثم قال واسرع هذه الدعوات إجابة دعوة الأخ بظهر الغيب
"The prayers of five people are accepted: the prayer of the oppressed until he takes revenge; the prayer of the pilgrim until he returns (home); the prayer of the warrior until he sits among his family; the prayer of the sick until he recovers; and the prayer of a brother for his brother in his absence. Then the Prophet (peace be upon him) said: Of all these prayers, the one that is accepted the quickest is the prayer of a brother for his brother in his absence."
