[16].Surah An-Nahl [The Bees] : Ayat 39-40

Ayat 39. In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars.

Ayat 40. Verily! Our Word unto a thing when We intend it, is only that We say unto it: "Be!" and it is.

Hazrat Ibn Abbas (May Allah be pleased with them) reported that the Messenger of Allah  [SAWW](PBUH) used to supplicate: "O Allah! To You I have submitted, and in You do I believe, and in You I put my trust, to You do I turn, and for You I argued. O Allah, I seek refuge with You through Your Power; there is none worthy of worship except You Alone; that You safeguard me against going astray. You are the Ever Living, the One Who sustains and protects all that exists; the One Who never dies, whereas human beings and jinn will all die".  [Muslim Book 35, Chapter 17, Hadith # 6561]. 

Lesson : as mentioned above in Surah An-Nahl Ayat 39. and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars. Even in the worst circumstances one should always have faith and trust in Allah, Allah (SWT) says "I am just as My slave thinks of Me when he remembers Me". Allah is more pleased with the repentance of His slave then any thing else.This Hadith highlights the merits of expecting good treatment of Allah. But this has to be backed by good actions, in the same way as one can hope for good results after ploughing and sowing seeds. It is obvious that one who accomplishes good deeds will expect good consequences, and one who does evil deeds will expect evil consequences. Allah will treat people according to their expectation that are founded on their actions, and the reward will match their deeds.
