That ʿItban bin Malik who was one of the companions of the Prophet ﷺ and one of the warriors of Badr, came to Messenger of Allah ﷺ.  

البخاري:٤٠٠٩حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ حَدَّثَنَا اللَّيْثُ عَنْ عُقَيْلٍ عَنِ ابْنِ شِهَابٍ أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ

أَنَّ عِتْبَانَ بْنَ مَالِكٍ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ مِمَّنْ شَهِدَ بَدْرًا مِنَ الأَنْصَارِ أَنَّهُ أَتَى رَسُولَ اللَّهِ ﷺ
