Belief in divine decree and submission to it

عَنْ أَبِیْ هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللہِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ

الْمُؤْمِنُ الْقَوِيُّ خَيْرٌ وَأَحَبُّ إِلَى اللہِ مِنَ الْمُؤْمِنِ الضَّعِيْفِ وَفِیْ كُلٍّ خَيْرٌ احْرِصْ عَلَى مَا يَنْفَعُكَ وَاسْتَعِنْ بِاللہِ وَلاَ تَعْجِزْ وَإِنْ أَصَابَكَ شَىْءٌ فَلاَ تَقُلْ لَوْ أَنِّی فَعَلْتُ كَانَ كَذَا وَكَذَا۔ وَلٰكِنْ قُلْ قَدَرُ اللہِ وَمَا شَاءَ فَعَلَ فَإِنَّ لَوْ تَفْتَحُ عَمَلَ الشَّيْطَانِ

Hazrat Abu Hurairah^ra relates that the Holy Prophet^sa said:

“A strong believer is better and more loved by Allah than a weak one. Out of all good things desire that which is most beneficial for you. Keep imploring Allah for help and do not give up. Should you be afflicted in any way, do not say: ‘Had I only done this and that things would have turned out so and so’; but say only: ‘Allah so determined and did as He willed’. The phrase ‘Had I only’ opens the gates of evil conduct.”

(Sahih Muslim, Kitab al-Qadr, Hadith 2664)
