Sulaiman bin Surad (May Allah be pleased with him) reported:
I was sitting with the Prophet (Sallallahu Alaihi Wasallam) when two men began to quarrel and curse each other and the face of one of them turned red and the veins of his neck were swollen (from rage).
Messenger of Allah (Sallallahu Alaihi Wasallam) said,
"I know of a word, if he were to utter that, his rage would vanish and that is:
A`udhu billahi minash-Shaitan nir-rajim (I seek refuge with Allah from Satan, the accursed).'' So they (Companions) said to him:
"The Prophet (Sallallahu Alaihi Wasallam) tells you to utter:
'I seek refuge with Allah from Satan, the accursed".
`Abdullah bin `Umar (Radiyallahu Anhuma) reported:
Messenger of Allah (Sallallahu Alaihi Wasallam) took hold of my shoulders and said,
"Be in the world like a stranger or a wayfarer".
Ibn `Umar (May Allah be pleased with them) used to say:
"When you survive till the evening, do not expect to live until the morning;
and when you survive until the morning, do not expect to live until the evening;
(do good deeds) when you are in good health before you fall sick, and (do good deeds) as long as you are alive before death strikes".
