وَكَيْفَ أَخَافُ مَآ أَشْرَكْتُمْ وَلَا تَخَافُونَ أَنَّكُمْ أَشْرَكْتُم بِٱللَّهِ مَا لَمْ يُنَزِّلْ بِهِۦ عَلَيْكُمْ سُلْطَٰنًۭا ۚ فَأَىُّ ٱلْفَرِيقَيْنِ أَحَقُّ بِٱلْأَمْنِ ۖ إِن كُنتُمْ تَعْلَمُونَ
How should I fear that which ye set up beside Him, when ye fear not to set up beside Allah that for which He hath revealed unto you no warrant? Which of the two factions hath more right to safety? (Answer me that) if ye have knowledge.

Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The Statement of Allah Ta'ala: "Those to whom We gave the Scripture (Jews and Christians) recognize him (Muhammad (saws)) as they recognize their own sons ..."
Narrated `Abdullah bin `Umar:
The Jews came to Allah's Messenger (ﷺ) and told him that a man and a woman from amongst them had committed illegal sexual intercourse. Allah's Messenger (ﷺ) said to them, "What do you find in the Torah (old Testament) about the legal punishment of Ar-Rajm (stoning)?" They replied, (But) we announce their crime and lash them." `Abdullah bin Salam said, "You are telling a lie; Torah contains the order of Rajm." They brought and opened the Torah and one of them solaced his hand on the Verse of Rajm and read the verses preceding and following it. `Abdullah bin Salam said to him, "Lift your hand." When he lifted his hand, the Verse of Rajm was written there. They said, "Muhammad has told the truth; the Torah has the Verse of Rajm. The Prophet (ﷺ) then gave the order that both of them should be stoned to death. (`Abdullah bin `Umar said, "I saw the man leaning over the woman to shelter her from the stones."
