It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whenever Allah Almighty bestows any blessing upon a servant of His and he says in response 'Al-hamdu lillah' (All praise is for Allah), he has certainly given thanks for that blessing. If he says these words a second time, Allah Almighty increases the reward for him, and if he says them a third time, Allah Almighty forgives his sins." This hadith is sahih, but the two Shaykhs did not record it; however, neither of them recorded the narration of Abu Mu'awiyah.
