It is narrated from Sayyiduna Abu Ubaydah bin al-Jarrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The heart of the son of Adam is like a sparrow; it turns over seven times a day." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

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: "Whoever fears (an enemy attack) sets out (on his journey) in the early part of the night, and whoever sets out in time reaches his destination. Beware! The merchandise of Allah is very costly. Beware! The merchandise of Allah is very precious (and it is Paradise)." 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 Ubayy bin Ka'b (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever is afraid sets off in the first part of the night, and whoever sets off reaches the destination. Beware! The merchandise of Allah is very costly. Remember! The merchandise of Allah is very precious, and it is Paradise. The quaking (of the Hour) has come, followed by another that will cause trembling; death has arrived with all its hardships."
