My question is should we view the tragedy of Karbala moreso as a praise of the Ahlul Bayt or should we view it in terms of its broader messages (such as justice and imaan and oppression) without so much focus on the Ahlul Bayt? My understanding of Karbala was not with a focus on the ahlul bayt, but of the universal ideas of divine justice and truth. Also how much should we use the wasila of the Ahlul Bayt in dua?

Many lessons can be derived from the tragedy of Karbala, but it also pains us to hear what happened to the household of the prophet (as). This is so when we have developed a love for them.

There is no limit on tawassul.
