✅ Answer: Some of the recommended actions during the month of Rajab include:

1⃣ Abu Ma'shar says: "When the month of Rajab entered, Imam Sadiq (a.s) used to recite the following supplication every day of the month of Rajab:

خَابَ الْوَافِدُونَ عَلَی غَیْرِکَ وَ خَسِرَ الْمُتَعَرِّضُونَ إِلَّا لَکَ وَ ضَاعَ الْمُلِمُّونَ إِلَّا بِکَ وَ أَجْدَبَ الْمُنْتَجِعُونَ إِلَّا مَنِ انْتَجَعَ فَضْلَکَ بَابُکَ مَفْتُوحٌ لِلرَّاغِبِینَ وَ خَیْرُکَ مَبْذُولٌ لِلطَّالِبِینَ وَ فَضْلُکَ مُبَاحٌ لِلسَّائِلِینَ وَ نَیْلُکَ مُتَاحٌ لِلْآمِلِینَ وَ رِزْقُکَ مَبْسُوطٌ لِمَنْ عَصَاکَ وَ حِلْمُکَ مُعْتَرِضٌ لِمَنْ نَاوَاکَ عَادَتُکَ الْإِحْسَانُ إِلَی الْمُسِیئِینَ وَ سَبِیلُکَ الْإِبْقَاءُ عَلَی الْمُعْتَدِینَ اللَّهُمَّ فَاهْدِنِی هُدَی الْمُهْتَدِینَ وَ ارْزُقْنِی اجْتِهَادَ الْمُجْتَهِدِینَ وَ لَا تَجْعَلْنِی مِنَ الْغَافِلِینَ الْمُبْعَدِینَ وَ اغْفِرْ لِی یَوْمَ الدِّین

2⃣ Yunus ibn Zabian says: "I was with Imam Sadiq (a.s), and Muali ibn Khunays entered while it was the month of Rajab. So they discussed and recited a supplication during the month of Rajab. Muali said, 'O my master, teach me a supplication that encompasses everything that the Shia has entrusted to his Lord in his books.' The Imam said: 'Say the following:

اللَّهُمَّ إِنِّی أَسْأَلُکَ صَبْرَ الشَّاکِرِینَ لَکَ وَ عَمَلَ الْخَائِفِینَ مِنْکَ وَ یَقِینَ الْعَابِدِینَ لَکَ اللَّهُمَّ أَنْتَ الْعَلِیُّ الْعَظِیمُ وَ أَنَا عَبْدُکَ الْبَائِسُ الْفَقِیرُ وَ أَنْتَ الْغَنِیُّ الْحَمِیدُ وَ أَنَا الْعَبْدُ الذَّلِیلُ اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ عَلَی آلِ مُحَمَّدٍ وَ امْنُنْ بِغِنَاکَ عَلَی فَقْرِی وَ بِحِلْمِکَ عَلَی جَهْلِی وَ بِقُوَّتِکَ عَلَی ضَعْفِی یَا قَوِیُّ یَا عَزِیزُ اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ الْأَوْصِیَاءِ الْمَرْضِیِّینَ وَ اکْفِنِی مَا أَهَمَّنِی مِنْ أَمْرِ الدُّنْیَا وَ الْآخِرَةِ یَا أَرْحَمَ الرَّاحِمِینَ

Then he said: 'O Muali, I swear by Allah, this supplication encompasses everything from the time of Ibrahim Khalil to the time of Muhammad (s.a.w.w).'

3⃣ Muhammad Sajjad says: "I asked Imam Sadiq (a.s), 'May I be your ransom! It is the month of Rajab; teach me a supplication so that Allah may grant me benefit through it.' The Imam replied: 'Write the following:

بِسْمِ اللَّهِ الرَّحْمنِ الرَّحِيم

On each day of the month of Rajab, recite this supplication in the morning and at the end of the day (or at the beginning of the night) and after your daily prayers:

یَا مَنْ أَرْجُوهُ لِکُلِّ خَیْرٍ وَ آمَنُ سَخَطَهُ عِنْدَ کُلِّ شَرٍّ یَا مَنْ یُعْطِی الْکَثِیرَ بِالْقَلِیلِ یَا مَنْ یُعْطِی مَنْ سَأَلَهُ یَا مَنْ یُعْطِی مَنْ لَمْ یَسْأَلْهُ وَ مَنْ لَمْ یَعْرِفْهُ تَحَنُّناً مِنْهُ وَ رَحْمَةً أَعْطِنِی بِمَسْأَلَتِی إِیَّاکَ جَمِیعَ خَیْرِ الدُّنْیَا و جَمِیعَ خَیْرِ الْآخِرَةِ وَ اصْرِفْ عَنِّی بِمَسْأَلَتِی إِیَّاکَ جَمِیعَ شَرِّ الدُّنْیَا وَ شَرِّ الْآخِرَةِ فَإِنَّهُ غَیْرُ مَنْقُوصٍ مَا أَعْطَیْتَ وَ زِدْنِی مِنْ فَضْلِکَ یَا کَرِیمُ

Then the Imam raised his left hand and moved his beard with it. While moving his right index finger (tawaluz), he recited this supplication:

یَا ذَا الْجَلَالِ وَ الْإِکْرَامِ یَا ذَا النَّعْمَاءِ وَ الْجُودِ یَا ذَا الْمَنِّ وَ الطَّوْلِ حَرِّمْ شَیْبَتِی عَلَی النَّارِ

4⃣قال أَبُو الْحسن مُوسَى بْنُ جَعْفَرٍ رَجَبٌ نَهَرٌ فِي الْجَنَّةِ أَشَدُّ بَيَاضاً مِنَ اللَّبَنِ وَ أَحْلَى مِنَ الْعَسَلِ فَمَنْ صَامَ يَوْماً مِنْ رَجَبٍ سَقَاهُ اللَّهُ مِنْ ذَلِكَ النَّهَر

4⃣ Imam Kazim (a.s) said: "Rajab is a river in paradise, whiter than milk and sweeter than honey. So, whoever fasts one day in the month of Rajab, Allah will make him drink from that river.

5⃣ قال أبوالحسن موسى بن جعفر رَجَبٌ شَهْرٌ عَظِيمٌ يُضَاعِفُ اللَّهُ فِيهِ الْحَسَنَات و يَمْحُو فِيه السَّيِّئَات مَنْ صَامَ يَوْماً مِنْ رَجَبٍ تَبَاعَدَتْ عَنْهُ النَّار مَسِيرَةَ سَنَةٍ و مَنْ صَامَ ثَلَاثَةَ أَيَّامٍ وَجَبَتْ لَهُ الْجَنَّةُ

Imam Kazim (a.s) said: "Indeed, Rajab is a great month. Allah multiplies the good deeds in it and erases sins. Whoever fasts one day of Rajab, the fire will be removed from him for a distance equivalent to a journey of one year, and whoever fasts three days, paradise becomes obligatory for him.

✅ Numerous traditions emphasize the virtue of fasting during the entire month of Rajab, especially on the first day, the fifteenth day, and the twenty-seventh day.

✅ For those unable to fast, giving charity in the form of a loaf of bread every day of the month of Rajab is recommended in hadith (Amali, p. 443).
