Sahib-e-Tarteeb making qadha of Zuhr Salaah after performing Asr Salaah
Q: I have a question about the Mas'ala of Sahib-e-Tarteeb:
1. If a person is Sahib-e-Tarteeb and he misses a prayer, for e.g. Zuhr. And then prays Asr and after praying Asr, he prays the Qaza of Zuhr. So obviously his Asr prayer is invalid. But what if after praying his Zuhr Qaza, he misses 6 more prayers. So he no longer remains Sahib-e-Tarteeb. So by missing 6 prayers will that Asr prayer which he offered becomes valid?
2. What if he then again offers all those 6 prayers' Qaza and again becomes Shahib-e-Tarteeb, will now his Asr prayer become invalid again?
