[15].Surah Al-Hjir [The Rocky Tract]: Ayat 94-96

Ayat 94. Therefore proclaim openly (Allah's Message Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikûn (polytheists, idolaters, and disbelievers, etc.).

Ayat 95. Truly! We will suffice you against the scoffers.

Ayat 96. Who set up along with Allah another ilâh (false god), they will come to know. 

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah  [SAWW](PBUH) delivered a Khutbah and said, "O people! Hajj (pilgrimage to the House of Allah) has been made incumbent upon you, so perform Hajj.'' A man inquired: "O Messenger of Allah  [SAWW], is it prescribed every year?'' He  [SAWW](PBUH) remained silent till the man repeated it thrice. Then he  [SAWW](PBUH) said, "Had I replied in the affirmative, it would have surely become obligatory, and you would not have been able to fulfill it.'' Afterwards he said, "Do not ask me so long as I do not impose anything upon you, because those who were before you were destroyed on account of their frequent questioning and their disagreement with their Prophets. So when  order you to do something, do it as far as you can; and when I forbid you from doing anything, eschew it.'' [Muslim Book 07, Chapter 71, Hadith # 3095]. 

1. Hajj is compulsory once in a lifetime for those who have the means for it.

2. Unnecessary questioning is disliked.

3. Those who believe in Allah and His Prophet  [SAWW](PBUH) are required to do what they are ordained and abstain from what they are forbidden.

This Hadith brings out the following points:
