It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) used to supplicate after the prayer: 'Allahumma inni a'udhu bika min al-kufri wal-faqri wa 'adhabil-qabr' (O Allah, I seek refuge in You from disbelief, poverty and the punishment of the grave). This hadith is sahih (authentic) on the condition of Muslim, for he used this very chain as evidence for: "There will be a tribulation in which the one sitting is better than the one standing", but the two Shaykhs did not record it.
