The Prophets and the shuhadaý (martyrs) are alive in al-barzakh as the Prophet (peace and blessings of Allaah be upon him) said: ýThe Prophets are alive and they pray in their graves.ý (Narrated by al-Mundhiri and al-Bayhaqi who classed it as saheeh because of corroborating reports in al-Saheehayn.)
