Muawiyah wrote to Al-Mughirah bin Shu'bah saying: "Tell me of something that you heard from the Messenger of Allah (SAW)." He said: "When the Messenger of Allah (SAW) finished praying, he would say: La Ilaha Illallah wahdahu la sharika lah, lahul-mulk wa lahul-hamd wa huwa 'ala kulli shay'in qadir. Allahumma la mani' lima a'taita wa la mu'tia lima mana'ta wa la yanfa'u dhal-jaddi minka al-jadd. (There is none worthy of worship except Allah (SAW) alone with no partner or associate. He is the Dominion and to Him be all praise, and He is able to do all things. O Allah, one can withhold what You have given and none can give what You have withheld, and no wealth or fortune can benefit anyone for from You comes all wealth and fortune.)'"

“Sa`d used to teach his children these words just as the Muktib teaches children, he would say: ‘Indeed, the Messenger of Allah (saws) used to seek refuge by saying them at the end of (every) Salat: O Allah I seek refuge in You from cowardliness, I seek refuge in You from miserliness, I seek refuge in You from feeble old age, and I seek refuge in You from the trial of the world, and the punishment of the grave (Allāhumma innī a`ūdhu bika minal-jubn, wa a`ūdhu bika minal-bukhl, wa a`ūdhu bika min ardhalil-`umur, wa a`ūdhu bika min fitnatid-dunyā wa `adhābil qabr).’”

“As the Prophet said (Allah bless him and give him peace):‘The most poetic saying spoken by the Arabs is the saying of Labid: “Everything but Allah is surely futile!'”

`Abd ar-Rahman b. Abu `Amira told that the Prophet said of Mu'awiya, "O God, make him a guide who is rightly guided and guide others by him." Tirmidhi transmitted it.

'Umar was heard to say, "Anyone who does not show mercy will not be shown mercy. Anyone who does not forgive will not be forgiven. Anyone who does not turn in repentance will not be turned to nor will he be protected or guarded."

He had a large head, a reddish white complexion, a large beard, large joints and large hands and feet. He had a long line of hair running from his chest to his navel and the hair on his head was thick and slightly wavy. He used to lean forward when walking as if he was walking uphill, and he was neither tall nor short, I have never seen anyone like him (ﷺ) before or since. ‘Ali bin Hakeem said in his hadeeth: ‘Ali bin Abi Talib (رضي الله عنه) described the Messenger of Allah (ﷺ) to us. He said: He had a large head and beautiful, slightly wavy hair.
