فَكَانَتِ الْأُمَمُ فِي رَجَاءٍ مِنَ الرُّسُلِ وَ وُرُودٍ مِنَ الْأَنْبِيَاءِ وَ لَئِنْ أُصِيبَتْ بِفَقْدِ نَبِيٍّ بَعْدَ نَبِيٍّ عَلَى عِظَمِ مَصَائِبِهِمْ وَ فَجَائِعِهَا بِهِمْ فَقَدْ كَانَتْ عَلَى سَعَةٍ مِنَ الْأَمَلِ وَ لَا مُصِيبَةٌ عَظُمَتْ وَ لَا رَزِيَّةٌ جَلَّتْ كَالْمُصِيبَةِ بِرَسُولِ اللَّهِ ( صلى الله عليه وآله ) لِأَنَّ اللَّهَ خَتَمَ بِهِ الْإِنْذَارَ وَ الْإِعْذَارَ وَ قَطَعَ بِهِ الِاحْتِجَاجَ وَ الْعُذْرَ بَيْنَهُ وَ بَيْنَ خَلْقِهِ وَ جَعَلَهُ بَابَهُ الَّذِي بَيْنَهُ وَ بَيْنَ عِبَادِهِ وَ مُهَيْمِنَهُ الَّذِي لَا يَقْبَلُ إِلَّا بِهِ وَ لَا قُرْبَةَ إِلَيْهِ إِلَّا بِطَاعَتِهِ So the communities lived in hope about the Messengers -as and the Prophets -as to come, if they were in difficult circumstances in the absence of a Prophet -as after their Prophet -as , in their great difficulties and disasters, so they were at the time in a state of hope.
And there have never been a difficulty which was greater, and nor a disaster greater like the difficulties with the Messenger of Allah -saww , because Allah -azwj Ended the Warnings, and the Reasons, and Cut-off through him -saww the Arguments, and the Reasons between Him -azwj and His -azwj creatures, and Made him -saww to be His -azwj Door which was between Him -azwj and His -azwj servants, and as His -azwj Authority which nothing would be Acceptable except by him -saww , nor any nearness to Him -azwj except by being obedient to him -saww .
وَ قَالَ فِي مُحْكَمِ كِتَابِهِ مَنْ يُطِعِ الرَّسُولَ فَقَدْ أَطاعَ اللَّهَ وَ مَنْ تَوَلَّى فَما أَرْسَلْناكَ عَلَيْهِمْ حَفِيظاً فَقَرَنَ طَاعَتَهُ بِطَاعَتِهِ وَ مَعْصِيَتَهُ بِمَعْصِيَتِهِ فَكَانَ ذَلِكَ دَلِيلًا عَلَى مَا فَوَّضَ إِلَيْهِ وَ شَاهِداً لَهُ عَلَى مَنِ اتَّبَعَهُ وَ عَصَاهُ وَ بَيَّنَ ذَلِكَ فِي غَيْرِ مَوْضِعٍ مِنَ الْكِتَابِ الْعَظِيمِ And He -azwj Said Decisively in His -azwj Book: “[4:80] Whoever obeys the Messenger, he indeed obeys Allah and whoever turns back, so We have not sent you as a keeper over them” .
So He -azwj Joined obedience to Himself -azwj with obedience to him -saww , and disobedience to Himself -azwj with disobedience to him -saww . So that was the Evidence which was Delegated to him -saww , and a Testimony against the one who obeys him -saww , and disobeys him -saww , and between that in other places from the Great Book.
