Incident: Shaikh Salim Bin Tsa and reading Qur’an Dream Explanation
Shaikh Salim Bin Tsa once visited Hamza Bin Al-Habib Al-Zayyat, God bless his soul, who had memorized the Holy Qur’an and read it with great devotion, seeking God’s pleasure, and saw him crying and rubbing his cheeks with dust. He exclaimed: “I call upon God’s protection for you. Oh Hamza, what is this crying?” Hamza replied: “Last night, I saw in a dream that the Day of Resurrection took place. The readers of the Qur’an were called in to stand before God Almighty, and I was among them. I then heard an amiable voice saying: ‘Only those who lived by the Qur’an should enter.’ I was in shock, so I began to withdraw. A voice called my name: “Where are you going to, Oh Hamza Bin Al-Zayyat?’ I cried out: ‘At thy command, Oh caller to my Lord.’ An angel then said to me: ‘Say: At Thy command Oh my Lord, At Thy command.’ So I repeated what the angel told me to say.
