📚Ma'ani al-Akhbar, p. 33

Imam Hasan al-Askari (peace be upon him) regarding the verse 'Guide us to the straight path' said: It means: Continue granting us the success by which we obeyed You in the past, so that we may continue to obey You in our future lives.

And the straight path is of two kinds: a path in this world and a path in the hereafter.

The straight path in this world is one that avoids excess and falls short of deficiency, remains moderate, and does not deviate towards falsehood. The other path is the believers' way to paradise, which is straight, and they do not deviate from it towards hell or anything else!

And Imam Sadiq (peace be upon him) regarding the verse 'Guide us to the straight path' said: It means: Guide us to the path that leads to Your love and to Your religion and prevents us from following our desires, which would lead to our destruction, or acting upon our opinions, which would lead to our ruin!

3⃣ عن محمد بن مسلم قال‏ سألت أبا عبدالله عن قول الله عزوجل ...«اهْدِنَا الصِّراطَ الْمُسْتَقِيمَ» صراط الأنبياء و هم الذين أنعم الله عليهم

📚Tafsir al-Ayyashi, vol. 1, p. 22

Muhammad ibn Muslim said: I asked Imam Sadiq (peace be upon him) about the saying of Allah, the Almighty 'Guide us to the straight path'; he said: It is the path of the prophets, and they are the ones whom Allah has blessed!

4⃣عن المفضل بن عمر قال: سَأَلْتُ أَبَاعَبْداللَّه عَنِ الصِّرَاطِ فَقَالَ هُوَ الطَّرِيقُ إِلَى مَعْرِفَةِ اللَّهِ عَزَّ وَ جَلَّ وَ هُمَا صِرَاطَانِ صِرَاطٌ في الدُّنْيَا و صِرَاطٌ فِي الْآخِرَةِ وَ أَمَّا الصِّرَاطُ الَّذِي في الدُّنْيَا فَهُوَ الْإِمَامُ الْمُفْتَرَضُ الطَّاعَةِ مَنْ عَرَفَهُ فِي الدُّنْيَا وَ اقْتَدَى بِهُدَاهُ مَرَّ عَلَى الصِّرَاطِ الَّذِي هُوَ جِسْرُ جَهَنَّمَ فِي الْآخِرَةِ و مَنْ لَمْ يَعْرِفْهُ في الدُّنْيَا زَلَّتْ قَدَمُهُ عَنِ الصِّرَاطِ فِي الْآخِرَةِ فَتَرَدَّى في نَارِ جَهَنَّم

📚Ma'ani al-Akhbar, p. 32

Mufaddal ibn Umar said: I asked Imam Sadiq (peace be upon him) about the straight path; the Imam said: It is the path of knowing Allah, and it consists of two paths: a path in this world and a path in the hereafter. The path in this world is the Imam whose obedience is obligatory. Whoever knows him and follows his guidance in this world will cross the path in the hereafter, which is a bridge over hell. Whoever does not know him in this world will slip on the path in the hereafter and fall into hell!

5⃣عن عُبَيْداللَّهِ بْنِ الْحَلَبِيِّ عَنْ أَبِي عَبْداللَّه قال: الصِّرَاطُ الْمُسْتَقِيمُ أَمِيرُ الْمُؤْمِنِينَ عَلِيّ
