Imam Ali (peace be upon him): As for the permission whose outward differs from its inward: Allah the Exalted forbade the believer from taking a disbeliever as a friend and guardian, and then bestowed a favour upon him by outwardly permitting him, at the time of taqiyya, to fast as the disbeliever fasts, to break his fast as he breaks his, to pray as he prays, to perform his deeds, and to show the disbeliever that he is doing so — and he has been granted a broad allowance in these outward actions. But inwardly, contrary to what he shows outwardly out of fear to the opponents who have gained mastery over the ummah, he must follow the religion of Allah. Allah the Exalted said: لا یَتَّخِذِ الْمُؤْمِنُونَ الْکافِرِینَ أَوْلِیاءَ مِنْ دُونِ الْمُؤْمِنِینَ وَ مَنْ یَفْعَلْ ذلِکَ فَلَیْسَ مِنَ اللهِ فِی شَیْءٍ إِلَّا أَنْ تَتَّقُوا مِنْهُمْ تُقاةً وَ یُحَذِّرُکُمُ اللهُ نَفْسَهُ [Let not the believers take the disbelievers as friends rather than the believers; and whoever does that has nothing to do with Allah in anything, unless you guard yourselves against them out of taqiyya (protective caution), and Allah makes you cautious of Himself]. So this is a permission by which Allah, out of mercy, has done good to the believers, so that they may make use of it outwardly at the time of taqiyya. And the Messenger of Allah (peace be upon him and his family) said: 'Indeed Allah loves that His permissions be taken up, just as He loves that His obligations be acted upon.'
