The need for steadfastness

Abu Hurairah (RA) reported:

The Messenger of Allah (SAW) said,

"The believer is not stung from the same hole twice."

(Bukhari, Vol. 8, #6133; Muslim bi Sharh Nawawi, #7423)

"Say (in affirmation): I believe in Allah, and thereafter be steadfast."

(Muslim bi Sharh Nawawi, #158; Riyadh Saleheen of Nawawi, #85)

"There will not cease to be a group of my Ummah who are obedient to Allah's orders. They will not be harmed by those who desert them, nor by those who oppose them, until Allah's order comes about, i.e, end of this world, ..."

(Bukhari, Vol. 4, #3641; Muslim bi Sharh Nawawi, #4932)

'Have patience, a time will not come upon you except that what comes after it is worse than it until you meet your Lord. I heard this from your Prophet (SAW).'
