فَإِن كَذَّبُوكَ فَقُل رَّبُّكُمْ ذُو رَحْمَةٍۢ وَٰسِعَةٍۢ وَلَا يُرَدُّ بَأْسُهُۥ عَنِ ٱلْقَوْمِ ٱلْمُجْرِمِينَ
So if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing Mercy, and His wrath will never be withdrawn from guilty folk.

Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: The arrival of Al-Ash’ariyun and the people of Yemen
Narrated Alqama:
We were sitting with Ibn Masud when Khabbab came and said, "O Abu `Abdur-Rahman! Can these young fellows recite Qur'an as you do?" Ibn Mas`ud said, "If you wish I can order one of them to recite (Qur'an) for you ." Khabbab replied, "Yes. "Ibn Mas`ud said, "Recite, O 'Alqama!" On that, Zaid bin Hudair, the brother of Ziyad bin Hudair said, (to Ibn Mas`ud), "Why have you ordered 'Alqama to recite though he does not recite better than we?" Ibn Mas`ud said, "If you like, I would tell you what the Prophet (ﷺ) said about your nation and his (i.e. 'Alqama's) nation." So I recited fifty Verses from Sura-Maryam. `Abdullah (bin Mas`ud) said to Khabbab, "What do you think (about 'Alqama's recitation)?" Khabbab said, "He has recited well." `Abdullah said, "Whatever I recite, 'Alqama recites." Then `Abdullah turned towards Khabbab and saw that he was wearing a gold ring, whereupon he said, "Hasn't the time for its throwing away come yet?" Khabbab said, "You will not see me wearing it after today," and he throw it away.
