He prayed one rak'ah of the 'Asr prayer, then the sun set. Did he catch the 'Asr prayer?

Question : Or also. What I said regarding al-Bukhari: either one rak'ah, or one cannot manage anything but al-Fatihah.

Answer : There is a basis that al-Fatihah is obligatory. I missed al-Fatihah. Welcome. This is a different issue; this is a second issue, meaning: with what does one leave the rak'ah with the imam? A second issue that does not distinguish. But the meaning, for example, if a person says the takbir for entering the state of prayer before the sun sets, recites al-Fatihah, bows, and prostrates, then stands for the second rak'ah after the sun has set, we say that he caught the 'Asr prayer because he prayed one rak'ah before the sun set.
