Hadith.5287 - It is narrated from Muhammad ibn Qays from Abu Jafar Imam Muhammad ibn Ali Al-Baqir (as) who said: "The Commander of the Faithful (as) ruled concerning a man who lost one of his eyes that an ostrich egg should be taken, and the man's healthy eye should be covered so he cannot see with it. Then, his vision should be measured to its limit, and the distance between the range of his injured eye and his healthy eye should be calculated. Compensation should be paid accordingly based on that measurement."

Hadith.5288 - It is narrated from Ibn Abi Umair from Hisham ibn Salim from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) who said: "Everything in the human body that exists in pairs carries the full blood money (diyya) for both, and half the blood money for one. And whatever exists as a single part in the body carries the full blood money."

Hadith.5289 - It is narrated from Ibn Mahbub from Abdul Wahhab ibn Al-Sabbah from Ali from Abu Basir from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) that he said regarding a man who was struck in his ear and claimed that one of his ears had diminished in hearing. Imam (as) said: "The injured ear should be tightly bound, and the healthy ear should be left open. A bell should be struck in front of his face, and he should be asked to listen. If the sound of the bell becomes faint for him, its position should be noted. Then, the bell should be taken behind him and rung until the sound fades for him; when it fades, its position should be marked. The distance between the two positions is then measured. If they are equal, it is known that he has spoken the truth. Then, the bell should be taken to his right side and rung until the sound fades, and its position should be marked. Similarly, the bell should be taken to his left side and rung until the sound fades, and its position should be marked. If the distances are equal, it is confirmed that he has spoken the truth." Imam (as) further said: "Then the affected ear should be opened, and the healthy ear should be tightly bound. The bell should be rung in front of him, and the process repeated as it was initially done with the healthy ear. Then, the difference between the healthy and the affected ear should be measured, and compensation determined accordingly."

Hadith.5290 - It is narrated from Ibn Mahbub from his father from Hammad ibn Ziyad from Sulayman ibn Khalid from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq (as) who said: I asked Imam (as) about a man who struck another man's ear with a bone, and the man claimed that he had completely lost his hearing. Imam (as) said: "He should be given a respite for one year, and two just witnesses should observe him. If they testify that he heard and responded to hearing, then he has no right (to compensation). But if it cannot be confirmed that he heard, he should be made to swear an oath, and then he should be given the full compensation (blood money)." I asked: "What if he regains his hearing after receiving the compensation?" Imam (as) replied: "It is something Allah (swt) the Exalted has granted him." I then asked Imam (as) about someone who claimed he could no longer see with his eye. Imam (as) said: "He should be given a respite for one year, and after the year, he should swear an oath that he cannot see, and then he should be given the full compensation (blood money)." I asked: "What if he regains his sight after that?" Imam (as) replied: "It is something Allah (swt) has granted him."
