Is it obligatory to shorten the four-rak'ah prayer for the traveler?

The questioner : Yes. It is called that according to the stronger position, and the shortening is obligatory. I mean, what does the hadith of A'ishah mean the first time?

The Shaykh : It only clarifies the state of the prayer; it was the first to be relaxed, and then it was increased. Yes, I agree with the first obligatory prayer, meaning its meaning did not change and nothing was added to it. The fact that the Companions (may Allah be pleased with them) agreed to pray behind Uthman without sitting for the first tashahhud or praying alone indicates that it is not obligatory. And something that the majority of the Companions did not do, a person cannot say is obligatory.
