وَجَاهِدُوا فِي اللَّهِ حَقَّ جِهَادِهِ هُوَ اجْتَبَاكُمْ وَمَا جَعَلَ عَلَيْكُمْ فِي الدِّينِ مِنْ حَرَجٍ مِّلَّةَ أَبِيكُمْ إِبْرَاهِيمَ هُوَ سَمَّاكُمُ الْمُسْلِمينَ مِن قَبْلُ وَفِي هَذَا لِيَكُونَ الرَّسُولُ شَهِيدًا عَلَيْكُمْ وَتَكُونُوا شُهَدَاء عَلَى النَّاسِ فَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ وَاعْتَصِمُوا بِاللَّهِ هُوَ مَوْلَاكُمْ فَنِعْمَ الْمَوْلَى وَنِعْمَ النَّصِيرُ
﴿٧٨﴾
سورة الحج
(22/78) And strive hard in Allah with its due. He has chosen you. Has not laid upon you any hardship in the Religion which is the religion of your father Abraham. He named you Muslims (submitters to Allah) before and in this (the Qur’ân), that the Messenger may be a witness to you, and you may be bearers of witnesses to people. Therefore keep up the Prayer and pay alms, hold fast to Allah (disappear in Allah). He is your Friend. How excellent Friend, how excellent Helper.
Surah Al-Hajj
