URDU TRANSLATION:
We can see in the hadith that the word نُصَلِّي is used which means while praying, Only 12 people remained with the Prophet. We also know that it was Friday prayer not morning or Isha prayer (that we can expact less numbers of prople).
The verse of holy Quran says " And when they see merchandise or sport they break up for It, and leave you standing. Say: What is with Allah is better than sport and (better) than merchandise, and Allah is the best of Sustainers." (62:11)
