If it is not possible to extract it...
If it is not possible to extract it, the toilet must be permanently sealed so that it can never be used in the future. The removal of sacred objects from Najasat and their purification is not Wajib only on the owner or those who have made them Najis, it is Wajib upon all those Muslims who are aware of it. But it is a Wajib al-Kifai, that is if one performs it, others are relieved of their duty.
If in spite of all of them being aware of it, none of them performs this duty, all of them shall be held responsible. 5-It is Harām to touch the letters of the Qur’an without Wuzu (ritual ablution), whether with hands or lips or with any other part of the body. There are detailed laws for this and those who wish to learn more should refer to Urwathul Wuthqa, section of Wuzu, Masla nos. 1-19.
6-At the conclusion Makasibul Muhrima Shaykh Ansari writes that a group of scholars believe that selling and buying Qur’an is Harām. Their decision is based on a tradition that we cannot narrate here. On the basis of this we should only make intention of buying and selling the covering and paper etc and not ‘the cost of Qur’an’. The buyer should pay the cost with the intention of giving hadiya to the seller.
That is he will not even touch the cover or the margins of Qur’an without Wuzu or with a Najis hand, whether wet or dry. He will not carry it without being with Wuzu. If he has to always carry Qur’an with him, he will always remain with Wuzu. One should not turn ones back to Qur’an or stretch our legs towards it. Not to place anything on top of Qur’an. Sit facing the Qibla while reciting the Qur’an. Qur’an should be recited in a pleasant tone, slowly and with thinking upon the meaning.
