✅ Based on the above narrations and others, entering Ihram for Hajj or Umrah is not valid except after an obligatory or voluntary prayer. If it is not the time for an obligatory prayer, one should perform two rakats or, according to Al-Tahzib, Vol. 5, p. 78, four or six rakats of voluntary prayer and then enter Ihram.

✅ According to narration 9, a menstruating woman who wants to enter Ihram should perform the ghusl for Ihram but not pray the Ihram prayer.

✅ According to narration 8, if someone enters Ihram without performing the prayer, it is incumbent upon him to repeat it.

اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْر
