عَنْ يَحْيَى بْنِ يَعْمَرَ عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((أَوَّلُ مَا يُحَاسَبُ بِهِ الْعَبْدُ صَلَاتُهُ، فَإِنْ كَانَ أَتَّمَهَا كُتِبَتْ لَهُ تَامَّةً وَإِنْ لَمْ يَكُنْ أَتَّمَهَا قَالَ اللَّهُ عَزَّ وَجَلَّ: انْظُرُوا هَلْ تَجِدُونَ لِعَبْدِي مِنْ تَطَوُّعٍ فَتُكَمِّلُوا بِهَا فَرِيضَتَهُ، ثُمَّ الزَّكَاةُ كَذَلِكَ ثُمَّ تُؤْخَذُ الْأَعْمَالُ عَلَى حَسْبِ ذَلِكَ))
A companion of the Messenger narrates that the Messenger of Allah, peace and blessings be upon him, said: The first thing for which a servant will be held accountable is his prayer. If he has completed it, it will be recorded as complete, and if there is any deficiency in it, Allah Almighty will say: Look, do you find any voluntary prayers of My servant? Complete his obligatory prayer with that. Then, zakat will be accounted for in the same way, and then other deeds as well.
