(Al-Baqara) 2 : 277
إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ وَأَقَامُوا الصَّلَاةَ وَآتَوُا الزَّكَاةَ لَهُمْ أَجْرُهُمْ عِنْدَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Indeed, those who believed and did righteous deeds, steadfast prayer, and pay the welfare tax, they have their rewards near their Lord, there shall be no fear upon them and for them will not be grieved.
One can only become a believer with Adhikr. And without becoming a believer, no prayer will be responded and no deed will be accepted by the Lord as explained in verse 2: 186. Today, as there is no group of believers anywhere in the world, the odd believer should follow the mode of prayer and lifestyle as explained in verses 7: 205-206. See explanation 2: 38 and 4: 142-143.
