For Business / Deal
It is a highly profitable transaction. Put your Tawakkul in Allah and be careful not to let Haram enter your wealth.
يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا عَدُوِّي وَعَدُوَّكُمْ أَوْلِيَاءَ تُلْقُونَ إِلَيْهِم بِالْمَوَدَّةِ وَقَدْ كَفَرُوا بِمَا جَاءَكُم مِّنَ الْحَقِّ يُخْرِجُونَ الرَّسُولَ وَإِيَّاكُمْ ۙ أَن تُؤْمِنُوا بِاللَّهِ رَبِّكُمْ إِن كُنتُمْ خَرَجْتُمْ جِهَادًا فِي سَبِيلِي وَابْتِغَاءَ مَرْضَاتِي ۚ تُسِرُّونَ إِلَيْهِم بِالْمَوَدَّةِ وَأَنَا أَعْلَمُ بِمَا أَخْفَيْتُمْ وَمَا أَعْلَنتُمْ ۚ وَمَن يَفْعَلْهُ مِنكُمْ فَقَدْ ضَلَّ سَوَاءَ السَّبِيلِ

O ye who believe! Take not my enemies and yours as friends (or protectors),- offering them (your) love, even though they have rejected the Truth that has come to you, and have (on the contrary) driven out the Prophet and yourselves (from your homes), (simply) because ye believe in Allah your Lord! If ye have come out to strive in My Way and to seek My Good Pleasure, (take them not as friends), holding secret converse of love (and friendship) with them: for I know full well all that ye conceal and all that ye reveal. And any of you that does this has strayed from the Straight Path.
