Mlango wa 816: Kitabu cha Dua na Maombi
وعنه أن رسول الله صلى الله عليه وسلم كان يقول: "دعوة المرء المسلم لأخيه بظهر الغيب مستجابة، عند رأسه ملك موكل كلما دعا لأخيه بخير قال الملك الموكل به: آمين، ولك بمثل" ((رواه مسلم)).
Kutoka kwa Abud-Darda' (Radhi za Allah ziwe juu yake) reported: "The Mjumbe wa Allah (Rehema na amani za Allah ziwe juu yake) said, "The dua of a Muislamu for his (Muislamu) brother in his absence will certainly be answered. Everytime he makes a dua for good for his brother, the angel appointed for this particular task says: 'A meen! May it be for you, too'."."
Abud-Darda' (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "The supplication of a Muslim for his (Muslim) brother in his absence will certainly be answered. Everytime he makes a supplication for good for his brother, the angel appointed for this particular task says: 'A meen! May it be for you, too'.".
