[Machine] 'Omar ibn al-Khattab said, "Do not be deceived by a person's prayer or fasting. Whoever wants to fast may do so, and whoever wants to pray may do so. However, a person who lacks integrity has no religion."  

البيهقي:١٢٦٩٤ – وَأَخْبَرَنَا أَبُو الْحُسَيْنِ بْنُ بِشْرَانَ بِبَغْدَادَ أنا إِسْمَاعِيلُ بْنُ مُحَمَّدٍ الصَّفَّارُ ثنا أَحْمَدُ بْنُ مَنْصُورٍ الرَّمَادِيُّ ثنا عَبْدُ الرَّزَّاقِ أنا مَعْمَرٌ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ قَالَ

قَالَ عُمَرُ بْنُ الْخَطَّابِ ؓ لَا يَغُرَّنَّكَ صَلَاةُ رَجُلٍ وَلَا صِيَامُهُ مَنْ شَاءَ صَامَ وَمَنْ شَاءَ صَلَّى وَلَكِنْ لَا دِينَ لِمَنْ لَا أَمَانَةَ لَهُ
