The Prophet sallahu allayhi wa salam said, “Whoever rejoices with his good deeds and grieves over his evil deeds, then that is the believer among you.” - [Sunan Tirmidhee (2165) and graded as “Saheeh” by Shaikh al-Albaanee]
"So if you see within yourself that your chest expands with obedience and constricts with sins, then this is a glad tiding for you, that you are from the believing slaves of Allaah and from His pious Auliyaa’. That is why the Prophet sallahu allayhi wa salam said, “and coolness (comfort) of my eyes has been provided in prayer” [Sunan al-Nasaa’ee (3939, 3940) and graded as “Saheeh” by Shaikh al-Albaanee]
-The Auliya of Allah-from Riyaadh Al Saliheen
Excerpt by http://foodiefahoodie.blogspot.com/2012/10/brief-comments-on-riyaadh-al-saaliheen_27.htmlSTILL... DON'T think much of yourself or think you are "safe." The way of the salaf was that they were in constant fear of being hypocrites and not doing enough. Always rushing towards doing good deeds, competing with one another in good. Umar Al-Khattab (radi Allahu anhu) was one to be recognized of being as such. Its a good thing to contemplate about our iman and seek to improve it always. I hope that this will be a reminder to give some relief to those who feel wounded by these schizo-shaytan battles... May Allah make it easy on all of you who seek nearness to him. Allahumma ameen.
It is reported that Al-Hasan Al-Basrî – Allâh have mercy on him – said:The believer does the best deeds yet is most fearful [that his deeds will not be accepted]. If he were to spend a mountain of wealth [in charity], he would not feel sure [of the reward] until he sees it. The more righteous and pious he becomes, the more he fears. But the hypocrite (munâfiq) says, ‘There are so many people, I will be forgiven, no problem.’ So he does wrong and evil deeds, yet holds foolish wishes about Allâh.
