What else could he do? He had no other place to preach until Allāh made things easy for him in Madinah, where he settled in his masjid teaching the people.

إذا لم تكُن إلَّا الأَسِنَّة مركبا ٭٭٭ فما حيلة المضطر إلَّا ركوبها If nothing remains but the spears to ride upon, Then what choice has the desperate one but to ride them? So invited to Allāh in their masjids, establish the Sunnah, and hold study circles if they allow you. Good will come from that — though their hearts may grow narrow and uneasy with your presence. But to abandon calling to Allah entirely — never! This is what I believe and incline toward: that we should call to Allāh in their masjids if we do not have masjids of our own where we can hold circles of knowledge. In earlier days, we too had no masjids in our area. We used to hold study circles in the masjids of those people — the Sufis we mentioned. We had no masjid of our own. We would study in their masjids, though sometimes they would forbid us, sometimes they would hide the books our brothers used to teach from, sometimes they would take away the Qur'āns, or say, “Leave, we are closing the masjid,” and extinguish the lamps. It was a struggle — sometimes they allowed us, sometimes they didn’t, sometimes they permitted the Tarāwīḥ prayer, and sometimes not. We persevered through all that until Allāh, Glorified and Exalted, brought relief. Now, praise be to Allāh, we have many flourishing masjids — this is the grace of Allāh upon us, and it requires gratitude. In our village there are now around nine Salafi masjids — five with pulpits for Friday sermons, and four for the daily prayers — all close to the people and benefitting them. We no longer need the masjids of those others, and we have returned to our own. So, call to Allāh wherever the opportunity presents itself. The Messenger of Allāh ﷺ used to go to the markets and call people to Allāh even though they threw stones at him — yet he remained patient until relief came. And to whom shall we leave the people? If we do not compete with those innovators in their masjids when we have none of our own, then to whom shall the people be left? The people can distinguish. When a Salafi speaks in a Hizbi masjid, they see the difference — they say: “This Hizhi has no knowledge; this Salafi gave us a touching reminder, a beneficial lesson, rulings we learned from, we felt at peace.” Some will even greet him afterwards, thanking him and asking him to return. We, here in Ash-Shiḥr, have only one masjid, far from the people. Our brothers and sons go and preach to the people, and they listen, benefit, and learn to discern — so there is no harm in that. When our Shaykh Muqbil — may Allāh have mercy on him — once visited our town, Al-Ḥāmi, we had no masjids. He went to the least effected masjids of the innovators, Masjid Ar-Rawdah, and gave a fine lecture there, attended by a large crowd. That masjid belonged to them, but it was the only one we had. The brothers hosted him and arranged his lecture there — and there was nothing wrong with that, for we had no other masjid. Source: https://t.me/masjidsahabah/1145
