In one of my previous posts, I cited a reference from Deobandi Mufti Taqi Usmani about writing Surah al-Fatiha (the first chapter of the Qur'an) with blood and urine.
However, make no mistake, this is not simply a Deobandi quote, it is in fact originally a well known Mas'alah of the Hanafi school of thought. We seek refuge in Allah from such a blasphemy and disrespect to the Qur'an. Only the extremely misguided and astray Hanafis could allow for writing the Qur'an with impurities like blood or urine:
لَوْ رَعَفَ فَكَتَبَ الْفَاتِحَةَ بِالدَّمِ عَلَى جَبْهَتِهِ وَأَنْفِهِ جَازَ لِلِاسْتِشْفَاءِ، وَبِالْبَوْلِ أَيْضًا إنْ عَلِمَ فِيهِ شِفَاءً لَا بَأْسَ بِهِ
Translation: It is permissible to write the Fatiha with blood upon his forehead and his nose upon realizing it will result in cure to do so, and with urine also for the purpose of cure. There is no problem in it.
وَقَدْ عُلِمَ أَنَّهُ لَوْ كَتَبَ فَاتِحَةَ الْكِتَابِ أَوْ الْإِخْلَاصَ بِذَلِكَ الدَّمِ عَلَى جَبْهَتِهِ يَنْقَطِعُ فَلَا يُرَخَّصُ لَهُ فِيهِ؛ وَقِيلَ يُرَخَّصُ كَمَا رُخِّصَ فِي شُرْبِ الْخَمْرِ لِلْعَطْشَانِ وَأَكْلِ الْمَيْتَةِ فِي الْمَخْمَصَةِ وَهُوَ الْفَتْوَى.
Translation: And if he comes to know that writing Surah al-Fatiha of the Qur'an or Surah al-Ikhlas with blood upon the forehead, then there is no dispensation for this. But it is said there is a dispensation for it like the dispensation for drinking wine in a state of extreme thirst or eating carrion in a state of starvation, and upon this is the Fatwa.
