What we learn from Aashura - sacrifice and strong belief

Through the story of Umm Salama and Abu Salama, we can learn many lessons. One of them pertains to their sacrifice as they migrated from Mecca to Madina to be with the Messenger (Salla Allahu alayhi wa sallam)
There is a strong parallel between the comment made by the Messenger to Abu Bakr during migration and the comment Musa (alahis-salam) made to his people in his migration, both recorded in the Quran.
In al-Tawba, 9:40, the Messenger says to Abu Bakr, "don't worry, Allah is with us!"
In ash-Shu'ara, 26:62, Musa says to his people, "Ney, indeed my Lord is with me, He will guide me!"
