Allah has ninety-nine Names, i.e., one hundred minus one, and whoever believes in their meanings and acts accordingly, will enter Paradise; and Allah is witr (one) and loves 'the witr' (i.e., odd numbers).
Sahih al-Bukhari Book 80, Hadith 105
← Previous Hadith The Prophet (ﷺ) started ascending a high place or hill. A man (amongst his companions) ascended it and shouted in a loud voice, "La ilaha illal-lahu wallahu Akbar." (At that time) Allah's Messenger (ﷺ) was riding his mule. Allah's Messenger (ﷺ) said, "You are not calling upon a deaf or an absent one." and added, "O Abu Musa (or, O `Abdullah)! Shall I tell you a sentence from the treasure of Paradise?" I said, "Yes." He said, "La haul a wala quwwata illa billah,"

Sahih al-Bukhari Book 80, Hadith 104 Next Hadith → While we were waiting for `Abdullah (bin Mas`ud). Yazid bin Muawiya came. I said (to him), "Will you sit down?" He said, "No, but I will go into the house (of Ibn Mas`ud) and let your companion (Ibn Mas`ud) come out to you; and if he should not (come out), I will come out and sit (with you)." Then `Abdullah came out, holding the hand of Yazid, addressed us, saying, "I know that you are assembled here, but the reason that prevents me from coming out to you, is that Allah's Messenger (ﷺ) used to preach to us at intervals during the days, lest we should become bored."
