İbrahim 6:

•  Hani Musa(as) halkına demişti ki:' Allah(cc)'ın üzerinizdeki nimetini hatırlayın. Çünkü , O sizi , işkencenin en kötüsüne reva görüp oğullarınızı öldürüp ve kadınlarınızı da sağ bırakan firavundan kurtardı. Gerçekten bunda sizin için çok büyük bir bela (بَلاء) (imtahan ve tecrübe) vardır'.

  بَلاءٌ “ ” (balaun), “ ابَتلَاءٌ ” (ibtela-un).
  Raghib says this word has two meanings:
  - To obtain information about one’s welfare or to acquire information about him.
  - For the real condition of something to become known, whether good or bad.
  When the word is used for God, it would have only the second meaning, because God knows it all, and one cannot even imagine that He is unaware of any condition {T, R}. Therefore, the word’s basic meaning is to portray the reality.
  بَلِیَ “ ” (bali), “ يَبْلٰی ” (yabla) is used for a cloth to become old and worn. Because when a cloth has been worn out, its real condition comes to light. Therefore “ ابلَاءٌَ ” (bala) is used for a man’s real personality to come out during times of difficulties and misery. But it does not necessarily mean that identity of everything has to be bad. It can also be good. That is why it could also mean the real personality of  someone during happy times. There are two times when a man’s reality becomes manifest, times of misery and times of happiness. At both these times, his real self appears.
  اَلْمُبَالا ه “ ” (al-mubalah): to boast, or to pride oneself as to the better position in life against another {M}.
  اَبْتَلا “ ” (ibtelaa): to select, to choose {T}.
  In surah Al-Baqrah, the Bani Israel has been told Pharaoh’s nation perpetrated different excesses on you, but We delivered you from their oppression.
  The struggle between Right and Wrong goes on. In this struggle we get familiar with different facts of life. Sometimes one is faced with trying aspects and at other times with peaceful aspect of life’s happiness. This has been described by the Quran as “ اَبْتَلٰی ” (ibtela), meaning the different faces of life
  which keep appearing. In surah Al-Fajr, this meaning is made clear (see 89:15-16). This way man can determine as to see how far his capabilities go, because he can only face the difficult aspects of life to the extent to which his latent qualities have developed. These hurdles that he faces are actually a man’s opportunities for development of his own personality. This is what “ اَبْتَلٰی ” (ibtela).
  Surah Al-Baqrah says:
  
  2:144 And when his Sustainer provided Ibrahim, opportunities to
  develop his personality, through various laws... وَإِذِ ابْتَلَی إِبْرَاهِﻴْمَ رَبُّهُ بِکَلِمَاتٍ
  
  When, as per the laws of God, life’s many events (difficulties) came into his (Ibrahim’s) life, so that He viewed how far Ibrahim’s capabilities had developed. The way Ibrahim faced these difficulties (the way he reacted) made clear that his capabilities had developed to the utmost. That his capabilities had developed fully.
  فاَتَمََّهُنَّ “ ” (fatamahunna) as in 2:124, makes it clear that the concept of “ اَبْتَلٰی ” (ibtela) being a “test” from God, as we usually believe, is not what Quran thinks it to be. God doesn’t test anyone, He only provides man with opportunities so he can judge how capable he is, and may strive to do better.
  In surah Ad-Dahar, the Quran has used the word “ اَبْتَلٰی ” (ibtela), from which the meaning of latent capabilities becoming evident. It says that the human birth takes place due to the interaction of the male and female. The sperm is composed of such minute germs that they cannot even be seen without a
  microscope, but the whole human child is hidden in those tiny germs.
