The Prophet Understands What He Conveys; Torment is in Allah's Hands Not the Prophet's

Allah says, just as We mentioned the clear signs that testify and direct to the path of guidance, all the while chastising useless arguments and defiance,

كَذلِكَ نُفَصِّلُ الآيَـتِ

About verse 54: وَإِذَا جَاءَكَ الَّذِينَ يُؤْمِنُونَ (And when to you come those who believe ... ), there are two interpretations given by leading authorities in Tafs.ir:

1\. Most of them have declared it to be related to previous verses and event. In support, they refer to the narration about the event when the chiefs of Quraysh demanded through Abu Talib that his nephew should first remove the poor people around him, with whom they could not sit, and then they would come and listen to him, and think about it. Thereupon, it was Sayyidna ` Umar ؓ who advised that it did not matter much, for Muslims were sincere friends and if requested they would move out of the sitting so that the chiefs of Quraysh could listen to the Word of Allah and become Muslims.
