“Offer prayer on time, and if you reached the Imam leading them in prayers (on time), then perform it with them, and you will be safe with your prayer, otherwise it will be voluntary for you.”  

عَنِ النَّبِيِّ ﷺ قَالَ صَلِّ الصَّلاَةَ لِوَقْتِهَا فَإِنْ أَدْرَكْتَ الإِمَامَ يُصَلِّي بِهِمْ فَصَلِّ مَعَهُمْ وَقَدْ أَحْرَزْتَ صَلاَتَكَ وَإِلاَّ فَهِيَ نَافِلَةٌ لَكَ  

[Machine] My friend Khalil asked Abu Dharr, so he hit my thigh and said, "I asked my friend, meaning the Prophet ﷺ, so he said, 'Pray at its prescribed time. If you catch it, pray with them and do not say, 'I have already prayed, so I will not pray.'"  

سَأَلَتُ خَلِيلِي أَبَا ذَرٍّ فَضَرَبَ فَخِذِي وَقَالَ سَأَلْتُ خَلِيلِي يَعْنِي النَّبِيَّ ﷺ فَقَالَ صَلِّ لِمِيقَاتِهَافَإِنْ أَدْرَكْتَ فَصَلِّ مَعَهُمْ وَلَا تَقُولَنَّ إِنِّي قَدْ صَلَّيْتُ فَلَا أُصَلِّي  

[Machine] "The Messenger of Allah ﷺ said, 'O Abu Dharr, there will be leaders upon you who will prevent you from performing prayers. If you are able to catch up with them, then pray the prayer at its designated time and make your prayer voluntary along with them.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ يَا أَبَا ذَرٍّ إِنَّهَا سَتَكُونُ عَلَيْكُمْ أَئِمَّةٌ يُمِيتُونَ الصَّلَاةَ فَإِنْ أَدْرَكْتُمُوهُمْ فَصَلُّوا الصَّلَاةَ لِوَقْتِهَا وَاجْعَلُوا صَلَاتَكُمْ مَعَهُمْ نَافِلَةً  

[Machine] The messenger of Allah ﷺ said, "O Abu Dharr, there will be leaders upon you who will not establish the prayer. If you witness them, then pray the prayer at its time and join your prayer with theirs as Sunnah."  

قَالَ رَسُولُ اللهِ ﷺ «يَا أَبَا ذَرًّ إِنَّهَا سَتَكُونُ عَلَيْكُمْ أَئِمَّةٌ يُمِيتُونَ الصَّلَاةَ فَإِنْ أَدْرَكْتُمُوهُمْ فَصَلُّوا الصَّلَاةَ لِوَقْتِهَا وَاجْعَلُوا صَلَاتَكُمْ مَعَهُمْ نَافِلَةً»  

"صَلِّ الصَّلَاةَ لِوَقْتِهَا، فإِنْ أَدْرَكتَ الإِمَامَ يُصَلِّى بِهِم فَصَلِّ مَعَهُم، وَقدْ أَحْرَزْتَ صَلَاتَكَ، وَإِلَّا فَهى نَافِلَةٌ لَكَ".
