Hadith

 حدّثنا محمّد بن الحسن بن الوليد رحمه الله، قال: حدّثنا محمّد بن الحسن الصفّار بإسناده، عن العبّاس بن يزيد، قال: قلت لأبي عبد الله عليه السلام ذات يوم: جعلت فداك، قول الله عز وجل: (وَإِذَا رَأَيْتَ ثَمَّ رَأَيْتَ نَعِيماً وَمُلْكاً كَبِيرَاً). قال: فقال لي: إذا أدخل الله أهل الجنّة الجنّة، أرسل رسولاً إلى وليّ من أوليائه فيجد الحجبة على بابه، فيقولون له: قف حتّى نستأذن لك. فما يصل إليه رسول الله إلاّ بإذن، وهو قوله: (وَإِذَا رَأَيْتَ ثَمَّ رَأَيْتَ نَعِيماً وَمُلْكاً كَبِيرَاً).

 Mohammed bin al-Hasan bin al-Waleed (r) narrated to us that Mohammed bin al-Hasan as-Saffar related to him… that al-Abbas bin Yazid said: One day, I said to Abu Abdullah (a): Allah may make me your sacrifice. What is the meaning of: "If you were to see it, you would find it to be a great kingdom with great bounty (76:20)"? He said to me: "After Allah allows the people of Paradise to enter there, he sends a messenger to one of His disciples. The messenger will find on the door of that disciple some doorkeepers who will ask him to wait until they obtain permission for him. Hence, even the messenger of Allah cannot attend before the disciples before they are permitted. This is the meaning of Allah’s saying: "If you were to see it, you would find it to be a great kingdom with great bounty (67:20)"
