[23].Surah Al-Muminun [The Believers]:Ayat 31-32

৩১) তাদের পরে আমি অন্য এক যুগের জাতির উত্থান ঘটালাম৷ 
৩২) তারপর তাদের মধ্যে স্বয়ং তাদের সম্প্রদায়ের একজন রসূল পাঠালাম (যে তাদেরকে দাওয়াত দিল এ মর্মে যে,) আল্লাহর বন্দেগী করো, তোমাদের জন্য তিনি ছাড়া আর কোন মাবূদ নেই, তোমরা কি ভয় করো না?

Ayat 31. Then, after them, We created another generation.

Ayat 32. And We sent to them a Messenger from among themselves (saying): "Worship Allah! You have no other Ilah (God) but Him. Will you not then be afraid (of Him i.e. of His Punishment because of worshipping others besides Him)?"

[Tafseer] of ayat 31. Then Allah raised after them another generation. in ayat 32. And Allah sent to them a messenger from among themselves, (saying), "Worship Allah. ye have no other God but Him. Will ye not fear (Him)?" If this refers to any particular prophet, it must be Hud whose mission was to the 'Ad people, or to Salih PBUH, whose mission was to the Thamud people. That is the sequence after Noah PBUH. But 1 think that as the name is not mentioned, we are to understand in general the type of post-Flood prophets until we come later on to Moses PBUH and Essa PBUH (Jesus). The object here is not to recount the stories, but to show that the resistance of the wicked made no difference to the triumph of Allah's Holy Truth.

Hazrat Bara bin Azib (May Allah be pleased with them) reported: The Messenger of Allah [SAWW](PBUH) said, "When a believer is questioned in the grave, he testifies that, `there is no true god except Allah and Muhammad is the Messenger of Allah.' About him the Words of Allah, the Exalted, are: `Allah will keep firm those who believe, with the firm statement (The Testimony of Faith) in this world and the Hereafter)". (14:27)

[Al-Bukhari Book 06, Chapter 60, Hadith # 221]. 

Lesson : as mentioned above in Surah Al-Muminun Ayat 32.""Worship Allah! You have no other Ilah (God) but Him" This Hadith mentions both the parts of the Shahadah together, that is to say "La ilaha illallah, Muhammad-ur-Rasulullah'' (There is no true god except Allah, and Muhammad [SAWW](PBUH) is the Messenger of Allah). The questioning in the grave is beyond question and is a part of Muslim Belief. Every Muslim will, by the Grace of Allah, give their correct answers in respect of Tauhid and Risalah.
