Those who dint prostrate to Adam (as)

Here is a clear Hadees which proves that the AhlulBait (as) dint prostrate to Prophet Adam (as) when Allah (swt) ordered the angels to prostrate to Adam (as).

حدّثنا عبد الله بن محمد بن عبد الوهاب عن أبي الحسن محمد بن أحمد القواريري، عن أبي الحسين محمد بن عمّار، عن إسماعيل بن توبة، عن زياد بن عبد الله البكائي، عن سليمان بن الأعمش، عن أبي سعيد الخدري، قال: كنّا جلوساً مع رسول الله صلّى الله عليه وآله إذ أقبل إليه رجل فقال

يا رسول الله، أخبرني عن قول الله عزّ وجلّ لابليس: (أَسْتَكْبَرْتَ أمْ كُنْتَ مِنَ الْعَالِينَ) فمَن هم يا رسول الله الّذين هم أعلى من الملائكة؟ قال رسول الله صلّى الله عليه وآله: أنا وعليّ وفاطمة والحسن والحسين، كنّا في سرادق العرش نسبّح الله وتسبّح الملائكة بتسبيحنا قبل أن يخلق الله عزّ وجلّ آدم بألفي عام. فلمّا خلق الله عزّ وجلّ آدم، أمر الملائكة أن يسجدوا له، ولم يأمرنا بالسجود فسجدت الملائكة كلّهم إلاّ إبليس فانّه أبى ولم يسجد. فقال الله تبارك وتعالى: (أَسْتَكْبَرْتَ أمْ كُنْتَ مِنَ الْعَالِينَ) عنى من هؤلاء الخمسة المكتوبة أسماؤهم في سرادق العرش



Abdullah bin Mohammed bin Abdul-Wahab narrated to us from Abu al-Hasan Mohammed bin Ahmed al-Qawariri from Abu al-Hussein Mohammed bin Ammar from Ismaeel bin Tawba from Ziyad bin Abdullah al-Bukaai from Sulaiman bin al-Amish that Abu Saeed al-Khidri related:

We were sitting with the Prophet (s) when a man came and asked him:

"O Allah's Messenger, Allah says: 'Eblis, what prevented you from prostrating before what I have created with My own hands? Was it because of your pride or are you one of those who are exalted?' (38:75) Who are those exalted ones whose ranks are higher than the angels'?"

The Prophet (s) answered: Those are Ali, Fatima, al-Hasan, al-Hussein, and I. We were in the pavilion of the Divine Throne praising Allah. The angels were imitating us. That was two thousand years before the creation of Adam. When He created Adam, Allah, Powerful and Exalted is He, ordered the angels to prostrate themselves before him. Allah did not include us in this order. All of the angels therefore prostrated except Eblis who rejected to prostrate. Referring to the five individuals whose names are recorded on the pavilion of the Divine Throne, Allah said to Eblis, 'Was it because of your pride or are you one of those who are exalted?
