وَعَن عبد الله بن شَقِيق
قَالَ: كَانَ أَصْحَابُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: لَا يَرَوْنَ شَيْئًا مِنَ الْأَعْمَالِ تَركه كفر غير الصَّلَاة
Abdallah ibn Shaqiq said that the companions of God’s Messenger did not consider the abandonment of any good deeds but prayer to be infidelity.
