“Once ‘Ammar, a group and I went to visit abu ‘Abd Allah (a.s.), in al-Madinah and he asked, ‘For how long have you decided to stay in al-Madinah?’ ‘Ammar said, ‘We have sent our camels to pasture for fifteen days.’ He (the Imam) said, ‘Your decision to stay in the town of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, and performing salat (prayer) in the Masjid is a proper one. You should work for your next life for yourselves a great deal. A man can be very intelligent in the worldly matters and people say, “How intelligent he is!” In fact, a true intelligent person is one who is intelligent in matters of the next life.’”
