The Disbelievers can cause no Harm to the Believers

This is a parable that Allah made of the believers, in that, if they needed to, their association with the disbelievers will not harm them. Allah the Exalted said,

لاَّ يَتَّخِذِ الْمُؤْمِنُونَ الْكَـفِرِينَ أَوْلِيَآءَ مِن دُونِ الْمُؤْمِنِينَ وَمَن يَفْعَلْ ذَلِكَ فَلَيْسَ مِنَ اللَّهِ فِي شَىْءٍ إِلاَ أَن تَتَّقُواْ مِنْهُمْ تُقَـةً

ضَرَ‌بَ اللَّـهُ مَثَلًا لِّلَّذِينَ آمَنُوا امْرَ‌أَتَ فِرْ‌عَوْنَ إِذْ قَالَتْ رَ‌بِّ ابْنِ لِي عِندَكَ بَيْتًا فِي الْجَنَّةِ (And Allah has cited for the believers the example of the wife of Fir'aun (the Pharaoh), when she said, "My Lord, build for me, near You, a house in the Paradise...66:11) This is the example of the wife of Fir'aun (the Pharaoh) whose name was ` Asiyah bint Muzahim. When Musa (علیہ السلام) accomplished his task in defeating the sorcerers who embraced Mosaic faith, she too embraced the Mosaic faith and became a Muslim. Fir'aun ordered that she should be tortured severely and tormented harshly. According to some reports, her hands and feet were pegged with nails to the ground and a huge rock was placed on her chest, so that she might not be able to move. In this state she supplicated to Allah as mentioned in this verse. According to other reports, it was suggested that a huge rock be dropped on her. They had hardly dropped the rock and she prayed to Allah as quoted in the verse. Allah then showed Sayyidah 'Asiyah ؓ her house in Paradise, and while looking at this vision her soul departed. When the rock fell on her body, it was lifeless. [ Mazhari ].
