When entering restroom facilities, it is nice to be reminded of the many sunnahs that relate to using the bathroom, hygiene, etc. But is it haram to have a framed dua or Quranic verse hanging on the wall (in a picture frame)? Thank you in advance. Wasalaam.
It would be better if one would learn the prayers (duas) by heart and practice the sunnah. Over time it will become second nature and you would need no external form of reminding.
Below is a Hadith that prohibited prayer (salaat) in a bathroom but the classification is Daif.
It was narrated that Ibn 'Umar said: "Allah's Messenger prohibited prayer from being performed in seven places: The garbage dump, the slaughtering area, the graveyard, the commonly used road, the bathroom, in the area that camels rest at, and above the Ka'bah."
Also as per Fathul Bari vol.1 pg.197; Daarul Qur’aan
If a person forgets to read the Du’aa before entering the toilet, then the Du’aa should be read in one’s heart, not on the tongue. However, if the toilet and bathroom are combined, then before entering the actual place of toilet, one may read the Du’aa verbally, on condition one is not unclothed.
