Take this curtain of yours away, for its images come to my mind while I'm praying

‘Ā'ishah (may Allah be pleased with her) had a colorful patterned thin curtain made of wool that she used to cover a niche in her room. The Prophet (may Allah's peace and blessings be upon him) ordered her to remove it. He explained to her that its patterns and colors kept on appearing before his eyes during prayer, so he feared that it would distract him from being fully devoted to the prayer and from pondering its invocations and recitation and realizing its purposes of submission and humility to Allah, the Almighty.
