Doctor Saheb. I thought 'pushing it under the rug' was what our Beloved Rasoolullah taught us to do. Abu Hurairah (May Allah be pleased with him) reported: The Prophet (PBUH) said, "Allah will cover up on the Day of Resurrection the defects (faults) of the one who covers up the faults of the others in this world". [Muslim]. There is whole chapter in Riyad As Saliheen of Imam Nawawi on 'Covering the faults of Fellow Muslims.'
