It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "If you were to rely upon Allah Almighty as He truly deserves to be relied upon, He would provide for you just as He provides for the birds: they go out in the morning hungry and return in the evening with full stomachs." 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: "Give my Ummah glad tidings of honour, elevation and authority in the world, so long as they do not seek the world through the deeds of the Hereafter. Whoever seeks the world through the deeds of the Hereafter will have no share in the Hereafter." 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 Ka'b bin Iyad (may Allah be pleased with him) that he said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "Indeed, every nation has had a trial, and the trial of my Ummah is wealth." 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 Abu Musa al-Ash'ari (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever loves his worldly life harms his Hereafter, and whoever loves his Hereafter harms his worldly life; so prefer that which remains (the Hereafter) over that which perishes." This hadith is sahih (authentic).
