[Machine] I heard the Messenger of Allah ﷺ say, "Indeed, a person may pray, and perhaps he will not have from his prayer except one-tenth of it, or one-ninth of it, or one-eighth of it, or one-seventh of it, until he reaches the last count."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِنَّ الرَّجُلَ لَيُصَلِّي وَلَعَلَّهُ أَنْ لَا يَكُونَ لَهُ مِنْ صَلَاتِهِ إِلَّا عُشْرُهَا أَوْ تُسْعُهَا أَوْ ثُمْنُهَا أَوْ سُبْعُهَا حَتَّى انْتَهَى إِلَى آخِرِ الْعَدَدِ»  

I heard the apostle of Allah ﷺ say: A man returns after saying his prayer while a tenth part of his prayer, or a ninth part, or an eight part, or a seventh part, or a sixth part, or a fifth part, or a third part, or half of it, is recorded for him. (Using translation from Abū Dāʾūd 796)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «إِنَّ الرَّجُلَ لَيَنْصَرِفُ وَمَا كُتِبَ لَهُ إِلَّا عُشْرُ صَلَاتِهِ تُسْعُهَا ثُمْنُهَا سُبْعُهَا خُمْسُهَا رُبْعُهَا ثُلْثُهَا نِصْفُهَا»
