So he decided to wake up his student to go out and bring him some water.
So he decided to wake up his student to go out and bring him some water. "Oh Bahman Yar! My son Bahman Yar! Please wake up and bring me some drinking water from outside" he said repeatedly. "Why is there no water in the water-mug near your goodself. Sir?" asked Bahman Yar. "No!" replied Ibn Sina. Bahman Yar raised his head and saw heavy snowfall outside. The thrilling sound of the strong cold wind also made him nervous to go out. Again 'Ibn Sina grumbled: "Oh Bahman Yar! Why the delay?
Bring me some water, I am too thristy." Bahman Yar dared not come out of the warm blankets to face the cold weather outside the room. He was, therefore, putting forward lame excuses to his tutor. "Oh my respected tutor! It is harmful for you to drink water now that you have just come out of the warmth of thick blankets. It is better you go to sleep again till the early morning which is not far off" said Bahman Yar. "My son! Bring me water, I am too thirsty.
I myself am a medical expert and know better what is harmful than you do. I am unable to sleep, please bring me some water from outside" again appealed Ibn Sina' In response 'Bahman Yar' again put forward excuses and argued that he would catch cold and fall sick if he were to go out in that extreme cold weather. So saying he went back to sleep. There was dead silence everywhere and no sound of anything was to be heard.
Outside it was still pitch dark except the first light of Subhe Sadiq (true dawn) in the eastern horizon had commenced to appear. Suddendly the silence broke with a melodious voice of a muezzin - caller to prayer from the top of a minaret at the nearby mosque. After reciting some verses of the holy Qur'an, the muezzin in a loud voice said "Allaho Akber" - Allah is the Greatest. "Ash-hado an la ailaha illallah" - I bear witness that there is no god except Allah.
Both the tutor and his student quietly listened to the melodious voice of the muezzin. The call to prayers then proceeded to the words "Ash hado anna Muhammadan Rasoolullah" - I bear witness that Muhammed is the Messenger of Allah. On hearing this, Ibn Sina thought of taking the opportunity of responding to the repeated proposal made to him by 'Bahman yar'. He said; "Listen to me, oh my son Bahman Yar.
Now I wish to reply to your repeated suggestion." The student sat up to hear attentively of what his learned tutor abruptly wanted to say.
