Question
What is the ruling for someone who began to pray while performing tayammum due to the presence of a lion preventing him from reaching the water, and then the lion left while he was in prayer?
Answer
I say, and with God's success: His tayammum is invalid, and he should perform ablution and repeat the prayer; because the ability to access water nullifies tayammum even if he is in prayer. Refer to: Al-Bahr Al-Ra'iq 1: 160, Al-Radd Al-Muhtar 1: 170, and Sharh Al-Wiqayah p. 110, and God knows best.
