Riyad as-Salihin, 100

Abu Hurairah (May Allah be pleased with him) reported:

Messenger of Allah (ﷺ) said, "A strong believer is better and dearer to Allah than a weak one, and both are good. Adhere to that which is beneficial for you. Keep asking Allah for help and do not refrain from it. If you are afflicted in any way, do not say: 'If I had taken this or that step, it would have resulted into such and such,' but say only: 'Allah so determined and did as He willed.' The word 'if' opens the gates of satanic thoughts". <b>[Muslim]</b>.

السادس‏:‏ عن أبي هريرة رضي الله عنه قال‏:‏ قال رسول الله صلى الله عليه وسلم‏:‏ ‏

‏ المؤمن القوي خير وأحب إلى الله من المؤمن الضعيف وفي كل خير‏.‏ احرص على ما ينفعك، واستعن بالله ولا تعجز‏.‏ وإن أصابك شيء فلا تقل‏:‏ لو أني فعلت كان كذا وكذا، ولكن قل‏:‏ قدر الله، وما شاء فعل؛ فإن لو تفتح عمل الشيطان‏

‏ ‏(‏‏(‏ رواه مسلم‏)‏‏)‏‏.‏

<b>Guidance from the Hadith:</b><br> 1) It shows the believer’s keenness to strengthen his faith through performing acts of obedience to Allah and refraining from committing what He prohibited.<br> 2) A rational person who complies with the guidance of the Prophet (may Allah’s peace and blessings be upon him) is expected to adhere to what benefits him in his life and in his religion as well as refrain from anything that is of no benefit.<br> 3) It urges reliance on Allah for help in all affairs, no matter how minor; for indeed reliance on Allah negates helplessness.<br> 4) Part of the guidance of the Prophet (may Allah’s peace and blessings be upon him) is that a person completes his deed without laziness, and that he starts with what is more important then what is less in importance.<br> 5) The Hadith affirms fate and the obligation of feeling content with it, because everything happens according to a divine decree and predestination.<br> <br> <b>Benefit:</b><br> The Prophet’s saying: “adhere to what benefits you” instructs prioritizing beneficial acts according to their level of importance. So if there is a conflict between a religious benefit and a worldly benefit, the former takes precedence because if one’s religion is sound, his worldly life becomes sound and vice versa.<br> <br> <b>Words in the Hadith:</b><br> A strong believer means strong with regards to faith and abundant acts of worship.<br> A weak believer means weak with regards to faith and a small amount of acts of worship.<br> Do not feel helpless: helplessness here refers to the inability to perform good deeds.
