الآية رقم (81) - وَإِذْ أَخَذَ اللّهُ مِيثَاقَ النَّبِيِّيْنَ لَمَا آتَيْتُكُم مِّن كِتَابٍ وَحِكْمَةٍ ثُمَّ جَاءكُمْ رَسُولٌ مُّصَدِّقٌ لِّمَا مَعَكُمْ لَتُؤْمِنُنَّ بِهِ وَلَتَنصُرُنَّهُ قَالَ أَأَقْرَرْتُمْ وَأَخَذْتُمْ عَلَى ذَلِكُمْ إِصْرِي قَالُواْ أَقْرَرْنَا قَالَ فَاشْهَدُواْ وَأَنَاْ مَعَكُم مِّنَ الشَّاهِدِينَ
(81) - (And [recall, O People of the Scripture], when Allah took the covenant of the prophets, [saying], "Whatever I give you of the Scripture and wisdom and then there comes to you a messenger confirming what is with you, you [must] believe in him and support him." [Allah] said, "Have you acknowledged and taken upon that My commitment?" They said, "We have acknowledged it." He said, "Then bear witness, and I am with you among the witnesses.")
Allah (swt) tells that He has taken the covenant of every prophet He sent from Adam to Jesus (PBUT). So, no matter how much wisdom and knowledge of the Scripture Allah (swt) gives to anyone, this should not prevent them from following, believing in, and supporting a messenger sent by Allah (swt). This is a manifestation of the unity of the fiducial chain that prevents fanaticism. Every prophet believes in the Prophet sent before him. The sequence of messages from the day that Allah (swt) created man is a supportive, not obstinate approach.
(… إِصْرِي …) (…My commitment …): My covenant.
