Regarding The Statement Of The Prophet (ﷺ) "Every Prayer That One Does Not Perfect It Will Be Made Complete By The Voluntary Ones"
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ حُمَيْدٍ، عَنِ الْحَسَنِ، عَنْ رَجُلٍ، مِنْ بَنِي سَلِيطٍ عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم بِنَحْوِهِ .
The above-mentioned tradition has also been transmitted by Abu Hurairah through a different chain of narrators to the same effect.
