مَنْ وَكَّلَ رَجُلًا عَلَى إِمْضَاءِ أَمْرٍ مِنَ الْأُمُورِ فَالْوَكَالَةُ ثَابِتَةٌ أَبَداً حَتَّى يُعْلِمَهُ بِالْخُرُوجِ مِنْهَا- كَمَا أَعْلَمَهُ بِالدُّخُولِ فِيهَا[6].
Hadith.3381 - Jabir ibn Yazid and Mu'awiyah ibn Wahb narrated from Abu Abdullah (as) that Imam (as) said: "Whoever appoints a man as an agent to execute a matter, the agency remains valid permanently until he informs him of its termination, just as he informed him of its initiation."
