📚Al-Tahdhib, Vol. 2, p. 140

📚Al-Tahdhib, Vol. 2, p. 272

Imam Reza (peace be upon him) said: O so-and-so! When the time enters for you, then perform it (the prayer), for you do not know what will happen!

📚Al-Tahdhib, Vol. 2, p. 25

📚Al-Tahdhib, Vol. 2, p. 264

Imam Sadiq (peace be upon him) said in a hadith: Indeed, your own east and west (and horizon) are your responsibility, and it is not for people to investigate and seek!

7 عَنْ أَبِي هَاشِمٍ دَاوُدَ بْنِ الْقَاسِمِ الْجَعْفَرِيِّ عَنِ الرِّضَا أَنَّ أَمِيرَ الْمُؤْمِنِينَ قَالَ لِكُمَيْلِ بْنِ زِيَادٍ أَخُوكَ دِينُكَ فَاحْتَطْ لِدِينِكَ بِمَا شِئْتَ.

✅What is mentioned in the above question was not possible in the past, but today, with the advent of fast means of travel such as airplanes, such a situation may sometimes occur.

What is mentioned in the general narrations of the Ahl al-Bayt (peace be upon them) is that based on the east and west and the horizon of the place where the person is located, when the time for prayer has entered, it is obligatory to perform the required purification, whether wudu or ghusl or tayammum, and perform the prayer. Therefore, a person who has performed his prayer at the point of origin and, due to travel by a fast vehicle, arrives at a destination where the time for that prayer has not yet arrived, must once again perform his usual duty and pray when the time for that prayer enters. And if someone suggests the possibility of the obligation of that prayer being dropped, based on the numerous narrations of the Ahl al-Bayt (peace be upon them) regarding caution, he is required to perform the prayer again, and abandoning that prayer has no place from the perspective of the sayings of the Ahl al-Bayt (peace be upon them).

اللَّهُمَّ فَصَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْرَ
