This night is called Laylat Dahw al-Ard (the night at which the earth was spread on the water where the Holy Ka’bah is now situated). Being distinctively honorable, on this night the mercy of Almighty Allah is poured on people. A great reward is obtained by those who practice acts of worship on this night. Ali ibn al-Hasan al-Washsha’ has narrated that when he was young, he was with his father in the hospitality of Imam al-Rida (عليه السلام) on the twenty-fifth night of Dhu’l-Qa’dah. After they had their supper, Imam al-Rida (عليه السلام) said, “On the twenty-fifth night of Dhu’l-Qa’dah, Prophet Abraham was born, Prophet Jesus the son of Mary was born, and the earth was spread on the water where the Holy Ka’bah is now situated. Hence, if one observes fasting on this day, he will be given the reward of observing fasting sixty months.” According to another narration, Imam al-Rida (عليه السلام) added, “Verily, on this day, al-Qa’im (i.e. Imam al-Mahdi) will appear.”
Day of Dahw al-Ard
The twenty-fifth of Dhu’l-Qa’dah is one of the four days on which fasting is exclusively confirmed. According to a narration, to observe fasting on this day is equal to seventy year fasting. It also erases the sins of seventy years. According to another narration, to observe fasting on this day and to practice acts of worship at its night is equal (in reward) to one hundred year worship. Everything that is between the sky and the earth will ask God’s forgiveness for one who does these rites. On this day, the mercy of Almighty Allah has been spread. To practice acts of worship and hold sessions for mentioning Almighty Allah on this day bring about an abundant reward. Apart from fasting, acts of worship, remembrance of Almighty Allah, and bathing, there are two other acts that are advisably done on this day:
2 rakaat salaat
The books written by Shi’ite scholars of Qumm have mentioned that, on this day, it is recommended to offer, in the morning, a prayer consisting of two units, reciting in the each unit Surah al-Fātiḥah once and repeating Surah al-Shams (No. 91) five times. After accomplishment, the following invocation is said:
لا حَوْلَ وَ لا قُوَّةَ اِلا بِاللّٰهِ الْعَلِيِّ الْعَظِيمِ
Then, one may pray Almighty Allah for granting his needs and then say the following supplication:
يَا مُقِيلَ الْعَثَرَاتِ اَقِلْنِي عَثْرَتِي يَا مُجِيبَ الدَّعَوَاتِ اَجِبْ دَعْوَتِي يَا سَامِعَ الْاَصْوَاتِ اسْمَعْ صَوْتِي وَ ارْحَمْنِي وَ تَجَاوَزْ عَنْ سَيِّئَاتِي وَ مَا عِنْدِي يَا ذَا الْجَلالِ وَ الْاِكْرَامِ .
Supplication
In Misbah al-Mutahajjid, Shaykh al-Tusi has mentioned that it is recommended to say the following supplication on this day:

Visit tomb of Imam Ali ar-Rida (a)
In his epistle entitled al-Arba’at Ayyam (The Four Days), Sayyid al-Damad has mentioned that to visit the holy tomb of Imam Alī ibn Mūsā ar-Riḍā (عليه السلام) on the day; i.e. the Earth Spreading Day, is the most preferable act. Similarly, to visit his tomb on the first of Rajab is highly desirable; therefore, he has urged on it greatly.
