Am I obligated to command my non-observant female colleagues to wear the legal hijab, given the abundance of religious sources that speak of it, and am I obligated to boycott them in eating and sitting if they persist in their sins, knowing that I denounce their sins in my heart, and this is based on the hadith: "Indeed, the first deficiency that entered upon the Children of Israel was that a man would meet another man and say: 'O so-and-so, fear Allah and abandon what you are doing, for it is not lawful for you,' then he would meet him the next day, and that would not prevent him from being his eater, drinker, and sitter? When they did that, Allah struck the hearts of some of them against others"?
Denial by the heart is only sufficient in case of inability. It is incumbent upon a Muslim woman to repeatedly advise her immodestly dressed colleagues to wear the hijab, reminding them, as Allah Almighty says: "And remind, for indeed, the reminder benefits the believers."
There is no harm in sitting with or associating with those who persist in sin, as long as the advisor continues her advice and is not influenced by them. Rather, this is emphasized if her companionship reduces their sins or brings them closer to righteousness.
