one of my friend ask me these questions..i dont know a single one's answer so i m asking from u..here it goes.
- woh konsi masjid thi jo Allah ko pasand nahi thi,or Allah ne usko jalaney ka hukam dia tha...iska zikar Quran mian b hai?
dont know about the rest of questions but as far as i know ,yeh masjid Masjid zarar thi.os time pe Kafiroon ne ek masjid tameer ke thi magar wahan Muslims ke khilaf sazish ke liye gatherings rakhna chahtay the. Unhoon ne Prophet PBUH ko yeh request ke keh is masjid mei imamat karva dein takeh kisi ko shaq na ho.Magar Prophet PBUh kisi safar ke liye nikal gaye (i think it was some ghazwa) aur kaha ke wapisi pe imamat karvain ge.Jab wapis madinah ke kareeb pohanchay tou un pe wahee nazil hui aur is masjid ke muta'alik bataya gea.Is pe Prophet PBUH ne is masjid ko toR dene ka hukum diya (jalanay ka pata nahi)
Abhi is mukaam pe ek masjid tameer hai is event ke nishandahee ke liye.:)
