It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The person who wept out of fear of Allah, the Mighty and Majestic, will not enter the Fire, until milk returns into the udder; and the dust of the path of Allah, the Mighty and Majestic, and the smoke of Hell can never gather together in the nostrils of a Muslim." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever remembered Allah and his eyes overflowed with tears out of fear of Allah, so much that they reached the ground, Allah Almighty will not punish him on the Day of Resurrection." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
