Zayd bin Arqam reported, "I suffered from an eye ailment, and the Prophet ﷺ visited me. When I recovered, I went out, and the Messenger of Allah ﷺ said to me, 'What would you do if you were to lose your sight?'I replied, 'If I were to lose my sight, I would bear it patiently and seek Allah's reward.'He said, 'If you were to lose your sight and then bear it patiently, seeking Allah's reward, you would meet Allah with no sin upon you.'"Ismail said, "Then bear it patiently and seek Allah's reward, and Allah Most High will grant you Paradise."

عن زيد بن أرقم قال

أصابني رمد، فعادني النبي ﷺ، قال: فلما برأت خرجت قال: فقال لي رسول الله ﷺ: أرأيت لو كانت عيناك لما بهما ما كنت صانعا؟ قال: قلت: لو كانتا عيناي لما بهما صبرت واحتسبت قال: لو كانت عيناك لما بهما ثم صبرت واحتسبت للقيت الله عز وجل ولا ذنب لك. قال إسماعيل: ثم صبرت واحتسبت لأوجب الله تعالى لك الجنة.
