You will follow the ways of those before you step by step

It is narrated from Sayyiduna Amr bin Awf al-Muzani (may Allah be pleased with him) that we were sitting around the Messenger of Allah (peace and blessings be upon him) in his mosque when he (peace and blessings be upon him) said: "You will surely follow the ways of those before you, step by step, and you will surely take as they took: if a hand-span, then a hand-span; if a cubit, then a cubit; if an arm's length, then an arm's length; to the extent that if they entered the hole of a lizard (dabb), you would enter it too. Listen! The Children of Israel split in the time of Musa (peace be upon him) into seventy (70) sects, all of them astray except one, and that one was Islam and their Jama'ah. Then they split in the time of Isa (peace be upon him) into seventy-one (71) sects, all astray except one, and that one was Islam and their Jama'ah. Then you will split into seventy-two (72) sects, all of them astray except one, and that one will be Islam and their Jama'ah."
This is the end of the "Book of Knowledge".

It is narrated from Sayyiduna Abdullah al-Sunabihi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When the servant performs ablution and rinses his mouth, the (minor) sins leave his mouth; when he puts water into his nose and blows it out, the sins leave his nose; when he washes his face, the sins leave his face, until they leave even from beneath his eyelashes. When he washes his hands, the sins leave his hands, until they leave even from beneath the nails of his hands. When he wipes his head, the sins leave his head, until they leave even from his ears; and when he washes his feet, the sins leave his feet, until they leave even from beneath the nails of his feet. Then his walking to the mosque and his prayer become supererogatory (extra reward) for him."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it, and there is no hidden defect ('illah) in it. They recorded part of this text from the hadith of Uthman and Abu Hurayrah (may Allah be pleased with them both), but not in full. Abdullah al-Sunabihi is a well-known Companion.
