Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates: We complained to the Prophet (peace and blessings be upon him) about the heat of the sand, but he (peace and blessings be upon him) did not accept our complaint. He (peace and blessings be upon him) said: "Recite abundantly 'La hawla wa la quwwata illa billah' (There is no might and no power except with Allah), for it wards off ninety-nine doors of harm, the least of which is worry." (Allamah al-Haythami says:) I say: There is a hadith of Sayyiduna Jabir (may Allah be pleased with him) about offering prayer in intense heat, recorded by Abu Dawud and others, and it is other than this narration.
Al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat. Its chain contains a narrator, "Balhat", whom al-Uqayli declared da'if (weak) and Ibn Hibban declared thiqah (trustworthy).
