He then commanded Bilal to call for prayer. He called for prayer. They (the people) performed ablution and offered two rak'ahs of the morning prayer (sunnah prayer). He then commanded Bilal (to utter the iqamah, i.e. to summon the people to attend the prayer). He announced the prayer (i.e. uttered the iqamah) and he led them in the morning prayer.
