O Allaah protect us with Your preservation...
'Umar ibn al-Khattab (رضي الله عنه) would say in his sermons, ' O Allaah, protect us with Your preservation and keep us firm on Your command.'
A man once said to one of the Salaf, 'May Allaah preserve you,' to which he replied, 'My brother, do not ask that he be preserved, ask instead that his faith be preserved!' What he meant was to stress the importance of supplicating for the preservation of ones religion; this is because worldly preservation could be conferred on both the righteous and the sinner, but Allaah only safeguards the religion of the believer and comes between it and anything that would pollute it via numerous means, some of which the servant is unaware of and yet others he may dislike.
