Q. Is it permitted to use the word ‘peer-e-qibla’ as they do here in Sylhet?
To use the word “qibla” to describe one’s teacher, murshid or shaykh, is perhaps not the most suitable and better avoided. To use it merely to describe one’s teacher out of respect and not intending it literally would strictly speaking be permitted but as mentioned, other titles (alqab) would suffice and hence better avoided. Imam Ibn `Abidin writes:
“[…] to keep a name that does not remind him of worshipping Allah Most High or remembering the Messenger of Allah (Allah bless him and grant him peace) or a name the Muslims do not normally use and is disputed. It would be preferable not to keep such a name…”
التسمية باسم لم يذكره الله تعالى في عبادة ولا ذكره رسوله صلى الله عليه وسلم ولا يستعمله المسلمون تكلموا فيهوالأولى أن لا يفعل…
And Allah knows best.
 See Ibn `Abidin, Radd al-Muhtar, 6:417.
