Hanafi Fatwa: To Get Drunk At Night Does not Invalidate I'tikaaf

According to the Hanafi school of thought, if a person is in I'tikaaf (spiritual seclusion) – which is a type of worship in Islam – and he gets drunk at night, his I'tikaaf is not broken:

وَإِذَا سَكَّرَ المعتكف لَيْلًا لَمْ يُفْسِدْ اِعْتِكَافُهُ؛ لِأَنَّهُ تَنَاوُلٌ مَحْظُورُ الدِّينِ لَا مَحْظُورٌ الاِعْتِكَافُ

معتکف رات کو نشہ کرلے تو اس کا اعتکاف فاسد نہیں ہوگا۔ اس لیے کہ اس نے ایسی شے استعمال کی ہے جو دین کےخلاف ہے نہ کہ اعتکاف کے خلاف۔

Translation: And if the Mu'takif intoxicates at night, his I'tikaaf is not nullified, because intoxication is against the Religion, and not necessarily against I'tikaaf.
