[13].Surah Ar-Ra'd [The Thunder] : Ayat2

Ayat 2. Allah is He Who raised the heavens without any pillars that you can see. Then, He Istawa (rose above) the Throne (really in a manner that suits His Majesty). He has subjected the sun and the moon (to continue going round)! Each running (its course) for a term appointed. He regulates all affairs, explaining the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) in detail, that you may believe with certainty in the meeting with your Lord.    

Hazrat Muadh bin Anas (May Allah be pleased with him) reported: Messenger of Allah  [SAWW](PBUH) said, "Whoever gives up wearing elegant and expensive garments out of humbleness, when he can do so, Allah will call him on the Day of Resurrection and before all the creations, He will give him the choice to wear whichever garment of Iman he would like to wear.'' [At-Tirmidhi Hadith # 2481]. 

Lesson : as mentioned above in Surah Ar-Ra'd Ayat 02. "you may believe with certainty in the meeting with your Lord." To adopt humility and not to assert superiority over others, according to this Hadith, is an excellent act with Allah. `The clothes of Iman' imply those special clothings of Jannah that Allah has prepared for sincere believers only.
