Benefits of faith in Allah in life and after death

♊ belief in Allah is a condition for the validity and acceptance of acts of worship, and that polytheism and disbelief in Allah nullifies all acts of worship. Just as a prayer is not accepted without ablution, no act of worship is accepted without belief in Allah.
➡️ Allah the Almighty said: {مَنْ عَمِلَ صَلِحًا مِّن ذَكَرٍ أَوْ أُنثَىٰ وَهُوَ مُؤْمِنٌ فَلَنُحْيِيَنَّهُ حَيَوَةً طَيِّبَةً وَلَنَجْزِيَنَّهُمْ أَجْرَهُم بِأَحْسَنِ مَا كَانُوا يَعْمَلُونَ} [An-Nahl: 97], so Allah made belief along with righteous deeds a condition for a good life in this world and a good reward after death.
➡️ And Allah the Almighty said: {وَمَن يَعْمَلْ مِنَ الصَّلِحَتِ مِن ذَكَرٍ أَوْ أُنثَى وَهُوَ مُؤْمِنٌ فَأُوْلَئِكَ يَدْخُلُونَ الْجَنَّةَ وَلَا يُظْلَمُونَ نَقِيرًا} [An-Nisa: 124], so He made faith and righteous deeds a condition for entering Paradise.
➡️ And Allah the Almighty said: {وَمَن يَعْمَلْ مِنَ الصَّلِحَتِ وَهُوَ مُؤْمِنٌ فَلَا يَخَافُ ظُلْمًا وَلَا هَضْما} [Taha: 112], so Allah made faith and righteous deeds a condition for security and safety on the Day of Resurrection.
➡️ And Allah the Almighty said: {وَمَنْ أَرَادَ الْآخِرَةَ وَسَعَىٰ لَهَا سَعْيَهَا وَهُوَ مُؤْمِنٌ فَأُوْلَئِكَ كَانَ سَعْيُهُم مَشْكُورًا} [Al-Isra’: 19], so Allah made belief in Him a condition along with the desire for the Hereafter and striving for it in order for this effort to be accepted and appreciated.
