Bukhari

Narrated `Aisha: The Prophet heard a man (reciting Qur'an) in the Mosque, and he said, "May Allah bestow His Mercy upon him. No doubt, he made me remember such-and such Verses of such-and-such Sura which I dropped (from my memory). Narrated Aisha: The Prophet performed the Tahajjud prayer in my house, and then he heard the voice of `Abbad who was praying in the Mosque, and said, "O `Aisha! Is this `Abbad's voice?" I said, "Yes." He said, "O Allah! Be merciful to `Abbad!"

Qasim, Hasan al-Basri, Ibn Sirin, al-Zuhri, and Ata also considered the testimony of a blind person to be permissible. Imam Shabi said that if he is intelligent and understanding, then his testimony is permissible. Hakam said that in many matters, his testimony can be accepted. Al-Zuhri said, "Tell me, if Ibn Abbas (may Allah be pleased with them both) were to testify in a matter, could you reject it?" And Ibn Abbas (may Allah be pleased with them both), when he became blind, would send a person at sunset (to go outside the settlement and see whether the sun had completely set or not, and when that person would return and inform him that the sun had set), he would break his fast. Similarly, he would inquire about the rising of Fajr, and when he was told that Fajr had risen, he would perform two rak'ahs (the Sunnah of Fajr). Sulayman bin Yasar (may Allah have mercy on him) said, "When I sought permission to enter upon Aisha (may Allah be pleased with her), she recognized my voice and said, 'Sulayman, come in, for you are a slave. As long as anything (from the contract of manumission) remains upon you.'" Samurah bin Jundub (may Allah be pleased with him) considered the testimony of a veiled woman to be permissible.

Narrated `Abdullah bin `Umar: The Prophet said, "Bilal pronounces the Adhan when it is still night (before dawn), so eat and drink till the next Adhan is pronounced (or till you hear Ibn Um Maktum's Adhan)." Ibn Um Maktum was a blind man who would not pronounce the Adhan till he was told that it was dawn.

Narrated Al-Miswar bin Makhrama: Some outer garments were received the Prophet and my father (Makhrama) said to me, "Let us go to the Prophet so that he may give us something from the garments." So, my father stood at the door and spoke. The Prophet recognized his voice and came out carrying a garment and telling Makhrama the good qualities of that garment, adding, "I have kept this for you, I have sent this for you."
