The first deed for which a servant will be held accountable on the Day of Resurrection

اَبِيْ هُرَيْرَةَ رَضِيَ اللهُ عَنْهُ قَالَ : قَالَ رَسُوْلُ اللهِ صَلَّي اللهُ عَلَيْهِ وَ سَلَّمَ إنَّ أوَّلَ ما يُحَاسَبُ به العبدُ يومَ القيامةِ مِن عملِهِ صلاتُهُ، فإنْ صَلَحَتْ فقد أَفْلَحَ وَأَنْجَحَ، وإنْ فَسَدَتْ فقد خَابَ وخَسِرَ، فإنْ انْتَقَصَ مِن فَرِيضَتِهِ شيءٌ، قال الرَّبُّ -عزَّ وجلَّ-: انْظُرُوا هل لعبدي مِن تطَوُّعٍ فَيُكَمَّلَ بها ما انْتَقَصَ مِن الفريضةِ، ثم يكونُ سَائِرُ عملِهِ على ذلك -

Meaning:
Abu Hurairah (R) narrated that the Messenger of Allah صَلَّي اللهُ عَلَيْهِ وَ سَلَّمَ said: The first deed for which a servant will be held accountable on the Day of Resurrection will be his salah prayer ( صلاة المكتباة) . If it is perfect, then he has succeeded and got free, but if it is imperfect, then he has failed and lost. If anything is missing from his obligatory prayer, the Lord - the Almighty and Majestic - will say: Look into any voluntary prayers of my servent so that they can fulfil what was missing from his obligatory prayer. Then the rest of his deeds will be based on that ( rule ) .
