Hadith: I heard the Prophet (may Allah's peace and blessings be upon him) recite Sūrah At-Tūr during the Maghrib prayer. When he reached this verse: {Were they created by nothing? Or were they themselves the creators? Or did they create the heavens and the earth? Rather, they are not certain. Or have they the depositories [containing the provision] of your Lord? Or are they the controllers [of them]?}, it was as if my heart was about to take flight

عن جبير بن مطعم رضي الله عنه قال: سمعت النبي صلى الله عليه وسلم يقرأ في المغرب بالطُّور، فلما بلغ هذه الآية: ﴿أم خُلِقُوا من غير شيء أم هم الخالقون، أم خَلَقُوا السموات والأرض بل لا يوقنون، أم عندهم خزائن ربك أم هم المسيطرون﴾. قال: كاد قلبي أن يطير.
[صحيح] - [متفق عليه]

Jubayr ibn Mut‘im (may Allah be pleased with him) reported: I heard the Prophet (may Allah's peace and blessings be upon him) recite Sūrah At-Tūr during the Maghrib prayer. When he reached this verse: {Were they created by nothing? Or were they themselves the creators? Or did they create the heavens and the earth? Rather, they are not certain. Or have they the depositories [containing the provision] of your Lord? Or are they the controllers [of them]?}, it was as if my heart was about to take flight.

Explanation

In this Hadīth, Jubayr (may Allah be pleased with him) heard the Prophet (may Allah's peace and blessings be upon him) recite Sūrat At-Tūr in the first two Rak‘ahs of the Maghrib prayer, and that was when he came to free the captives after the battle of Badr. He embraced Islam after that.
