ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ۚ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ
Allah - there is no deity except Him. And upon Allah let the believers rely.
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِنَّ مِنْ أَزْوَٰجِكُمْ وَأَوْلَـٰدِكُمْ عَدُوًّا لَّكُمْ فَٱحْذَرُوهُمْ ۚ وَإِن تَعْفُوا۟ وَتَصْفَحُوا۟ وَتَغْفِرُوا۟ فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ
O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them. But if you pardon and overlook and forgive - then indeed, Allah is Forgiving and Merciful.
فَٱتَّقُوا۟ ٱللَّهَ مَا ٱسْتَطَعْتُمْ وَٱسْمَعُوا۟ وَأَطِيعُوا۟ وَأَنفِقُوا۟ خَيْرًا لِّأَنفُسِكُمْ ۗ وَمَن يُوقَ شُحَّ نَفْسِهِۦ فَأُو۟لَـٰٓئِكَ هُمُ ٱلْمُفْلِحُونَ
So fear Allah as much as you are able and listen and obey and spend [in the way of Allah]; it is better for your selves. And whoever is protected from the stinginess of his soul - it is those who will be the successful.
إِن تُقْرِضُوا۟ ٱللَّهَ قَرْضًا حَسَنًا يُضَـٰعِفْهُ لَكُمْ وَيَغْفِرْ لَكُمْ ۚ وَٱللَّهُ شَكُورٌ حَلِيمٌ
If you loan Allah a goodly loan, He will multiply it for you and forgive you. And Allah is Most Appreciative and Forbearing.
