[32]. Surah As-Sajdah [The Prostration]: Ayat 21

২১. গুরু শাস্তির পূর্বে আমি অবশ্যই তাদেরকে লঘু শাস্তি আস্বাদন করাব, যাতে তারা প্রত্যাবর্তন করে।

Ayat 21. And verily, Allah will make them taste of the near torment (i.e. the torment in the life of this world, i.e. disasters, calamities, etc.) prior to the supreme torment (in the Hereafter), in order that they may (repent and) return (i.e. accept Islam).

Tafseer of Surah Al Sajdah (The Prostration) Ayat 21. And indeed Allah will make them taste of the Penalty of this (life) prior to the supreme Penalty, in order that they may (repent and) return. The final Penalty is to come in the Hereafter. There is no doubt about it. But before it comes, a minor Penalty comes in this very life. It may be in some kind of misfortune, or it may be in the pangs of a tortured conscience or secret sorrow. But this minor Penalty may be really a mercy, as it gives them a chance of repentance and amendment.

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said,  ,  "Allah, the Exalted, says: 'I have no reward other than Jannah for a believing slave of Mine who remains patient for My sake when I take away his beloved one from among the inhabitants of the world".

[Al-Bukhari Book 08, Chapter 76, Hadith # 432].  

Lesson : as mentioned above in Surah As-Sajda Ayat 21 “Allah will make them taste of the near torment (i.e. the torment in the life of this world, i.e. disasters, calamities, etc ” Child, wife and parents, etc., are the dearest people to everyone. It is a great sign of Faith to accept their death as the Will of Allah, to bear their loss with patience. Wailing and saying nonsense things show weakness of Faith. The reward of patience on such tragedies is Jannah while the result of impatience is displeasure of Allah.
