1. Thank you for contacting us and we emphasize on our interest in submitting what can be to serve the truth and reality. We want to draw your attention to an important issue in your journey to seek the truth and pick the right path which is that you should search for the evidences that each side claim to prove the correctness of its view. So you should search for what the shia give as a proof to the obligation to follow the Ahlulbyte after the death of the prophet and do not look for the details at the present stage. If their argument were proven to you then you can look for explanations to their practices if you were convinced with them, you can practice them as well otherwise you can refuse to practice them. If you were to start searching for the explanations to the details of the practices then this might confuse you more.
2. The thing that the imams of the Ahlulbyte emphasized on is the mourning and expressing pain and passion because of the oppression that the Ahlulbyte undertook, the disasters and the pains that they faced. The course of practice that devotee chose to express the mentioned obligation is entirely personal. Some express their feelings towards Imam Hussein (Peace be upon him) and his companions and his household by crying, expressing their sadness and wearing black clothes. Others do so by slapping their chests. Some others use bleeding as a way to express they sympathy with the imam and his household and companions as they were killed and stabbed with spears, swards and arrows.
As long as the wound has not healed and the blood flows naturally from the wound, one can offer his prayers in such a state. This exception does not make the blood tahir, If you touched the wound with your hand, and it becomes najis with blood, you must purify it before offering the prayer.
I’tikaf is valid only if it takes place in a central mosque that most people in the town go to; it is not sufficient for it to be in any mosque in the town. It is also a condition in the validity of the I’tikaf that it takes place in a mosque in which the congregational prayer is being offered, or has been offered in it before even once – based on obligatory precaution. I’tikaf is not in order if it is in a room that is not a mosque. It is not permissible for the person during I’tikaf to leave the mosque unless for a religious or conventional necessity.
If the general trend in fishing is that the fish are removed out of the water alive and the business is based on not marketing fish found dead in the water, and the possibility of selling fish which has died in the water is because of error, one should not pay attention to such possibilities and the fish may be bought and eaten.
