It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he said: Whoever says 'La ilaha illallah' (There is no god but Allah) should say immediately after it 'Al-hamdu lillahi Rabbil-'alamin' (All praise is for Allah, Lord of the worlds). By this he meant this saying of Allah Almighty: "So call upon Him, making religion sincerely His. All praise is for Allah, Lord of the worlds." [Surah Ghafir: 65] This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "If a ball of lead like this one, and he (peace and blessings be upon him) pointed to something like a skull, were released from the heaven towards the earth, which is a distance of five hundred years, it would reach the earth before nightfall." And the Messenger of Allah (peace and blessings be upon him) recited these verses: "When the iron collars will be around their necks, and the chains; they will be dragged." [Surah Ghafir: 71] This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
