Sa'd was a very high ranking companion and a shaheed. Prophet Muhammad took much more care during his burial than he normally would, yet he still chided someone who said that he would go straight to heaven.Lesson: If you have bad akhlaq, even the prophet cannot help you against the consequences Later, Prophet Muhammad proposed Zaynab bint Jahash marry his adopted son and ex-slave Zayd ibn Haritha.
