[22].Surah Al-Hajj [The Pilgrimage]: Ayat 12-14

Ayat 12. He calls besides Allah unto that which hurts him not, nor profits him. That is a straying far away.

Ayat 13. He calls unto him whose harm is nearer than his profit; certainly, and evil Maula (patron) and certainly an evil friend!

Ayat 14. Truly, Allah will admit those who believe (in Islamic Monotheism) and do righteous good deeds (according to the Qur'an and the Sunnah) to Gardens underneath which rivers flow (in Paradise). Verily, Allah does what He wills.

[Tafseer] They call on such deities, besides Allah, as can neither hurt nor profit them: that is straying far indeed (from the Way)! To such minds religion does not mean high Endeavour, self-sacrifice for noble ends, the recognition of Allah's infinite world, but just a small concession to formalism, perhaps a present to an idol (literal or figurative), perhaps attendance at worship if it can be done without trouble! It is false gods they worship, and the more they worship, the more they stray. 13. (Perhaps) they call on one whose harm is nearer than his profit: evil, indeed, is the  patron, and evil the companion (for help)! Such false worship is not always neutral, bringing neither harm nor good. Perhaps the harm comes first, and there is no help from Allah. Such minds are themselves demoralized, and render themselves unfit for help! Verily Allah will admit those who believe and work righteous deeds, to Gardens, beneath which  rivers flow: for Allah carries out all that He plans. Allah is both true to His promise, and He has power to give full effect to His Will and Plan. 

Hazrat Anas (May Allah be pleased with him) reported that: The Messenger of Allah [SAWW](PBUH) said, "When Allah intends good for His slave, He punishes him in this world, but when He intends an evil for His slave, He does not hasten to take him to task but calls him to account on the Day of Resurrection.''

[At-Tirmidhi Hadith # 2396].

Lesson : as mentioned above in Surah Al-Hajj Ayat 14."Allah will admit those who believe (in Islamic Monotheism) and do righteous good deeds " This Hadith shows that, for a Muslim, trials are also a blessing in this world because his sins are forgiven in proportion to the trials he has to face and his reward is increased with the Will of Allah. Thus, a Muslim should always be patient and contented in the event of trial because without these qualities he will not have the privilege associated with them. In fact, his impatience would increase his sins even further.
