The Prophet (ﷺ) said, "O ' Abdur-bin Samura ! Do not seek to be a ruler, because if you are given authority on asking for it, then you will be held responsible for it; but if you are given it without asking for it, then you will be helped in it (by Allâh): and whenever you take an oath to do something and later you find that something else is better than the first; then do the better one and make expiation for your oath. [8:619-O.B]

The Prophet (ﷺ) said, "We (Muslims) are the last (to come) in the world, but (will be) foremost on the Day of Resurrection."Allâh's Messenger (ﷺ) also said, "By Allâh, if anyone of you insists on fulfilling an oath by which he may harm his family, he commits a sin, with Allâh, greater than that of dissolving his oath and making its expiation with that which Allâh has commanded." [See the (V.5:89)]." [8:621-O.B]

We were with the Prophet (ﷺ) and he was holding the hand of 'Umar bin Al-Khattab. 'Umar said to him, "O Allâh's Messenger (ﷺ)! You are dearer to me than everything except my ownself." The Prophet (ﷺ) said, "No, by Him in Whose Hand my soul is, (you will not have complete faith) till I am dearer to you than your ownself." Then 'Umar said to him, "However, now, by Allâh, you are dearer to me than my ownself." The Prophet (ﷺ) said, "Now, 'Umar, (now you are a believer)." [8:628-0.B]

I reached him (the Prophet (ﷺ) while in the shade of the Ka'ba; he was saying, "They are the losers, by the Lord of the Ka'ba ! They are the losers, by the Lord of the Ka'ba ! " I said (to myself), "What is wrong with me? Is anything improper detected in me? What is wrong with me?" Then I sat beside him and he kept on saying his statement. I could not remain quiet, and Allah knows in what sorrowful state I was at that time. So I said, Who are they (the losers)? Let my father and mother be sacrificed for you, O Allâh's Messenger (ﷺ)! " He said, "They are the wealthy people, except the one who does like this and like this and like this (i.e., spends of his wealth in Allâh's Cause)." [8:633-O.B]

Allâh's Messenger (ﷺ) said, "Any Muslim who has lost three of his children will not be touched by the Fire except that which will render Allâh's oath fulfilled." [1] [8:650-O.B]

The Prophet (ﷺ) said, "Allâh forgives my followers those (evil deeds) their ownselves may suggest to them as long as they do not act (on it) or speak. [8:657-O.B]
