Hakim al-Umma Hadhrat Mawlana Ashraf Ali Thanawi (may Allah have mercy on him) said,
“Under certain circumstances instructing and advising others is merely a praiseworthy action (mustahib, not an absolute essential). However, if this indulgence interferes in one’s essential (wajib) activities than this praiseworthy action becomes impermissible (ghair mubah).”
