"The Messenger of Allah ﷺ said: (About saying) La ilaha illah - no deed takes precedence over it and it does not leave any sin.'"  

ابن ماجة:٣٧٩٧حَدَّثَنَا إِبْرَاهِيمُ بْنُ الْمُنْذِرِ الْحِزَامِيُّ حَدَّثَنَا زَكَرِيَّا بْنُ مَنْظُورٍ حَدَّثَنِي مُحَمَّدُ بْنُ عُقْبَةَ عَنْ أُمِّ هَانِئٍ قَالَتْ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ إِلَهَ إِلاَّ اللَّهُ لاَ يَسْبِقُهَا عَمَلٌ وَلاَ تَتْرُكُ ذَنْبًا
