Which is better: traveling for da‘wah with the Jama‘at al-Tableegh or traveling to visit family and for treatment? Does traveling for treatment contradict the conviction that Allah is the Healer? What is the ruling on da‘wah with the Jama‘at al-Tableegh in light of the說法 that da‘wah has become an individual obligation (fard ‘ayn)?

There is no harm in prioritizing going out for da‘wah (proselytization) over traveling to visit family or for medical treatment, unless doing so would lead to the illness taking hold or worsening, in which which case treatment must be prioritized. Similarly, if your absence from your family leads to neglecting their rights or abandoning their affairs, then you must travel to them. Da‘wah is not confined to travel; it can be performed in your own country and with your family. Seeking medical treatment does not contradict the belief that Allah is the Healer; rather, it is recommended and is a form of reliance upon Allah.
