Hazrat Aisha (may Allah be pleased with her) says that the fast of Arafah is an expiation for the sins of half a year. Hazrat Mujahid says that it is an expiation for the sins of one year.

Hazrat Humaid al-Tawil says that once it was mentioned before Hasan that the reward for fasting on the Day of Arafah is equal to the reward of fasting for a whole year. Upon hearing this, Hasan said that in my opinion, no day has any superiority over another day. And except for Laylat al-Qadr, no night has any superiority over another night. The Night of Qadr is better than a thousand nights. I saw Hazrat Uthman bin Abi al-As that he used to fast on the Day of Arafah, and due to the intense heat, water would be sprinkled on him for coolness.

It is narrated from Hazrat Abu Ayyub Ansari that the Messenger of Allah, peace and blessings be upon him, said: Whoever fasts in Ramadan and then also keeps six fasts in Shawwal, it is as if he has fasted for the whole year.

Hazrat Abu Musa says that when the observance of six voluntary fasts after Ramadan was mentioned before Hasan, he would say that Allah Almighty grants the reward of fasting for the whole year for the fasts of this month.

Hazrat Aisha (may Allah be pleased with her) said that I used to have to make up missed fasts of Ramadan, and I would observe these fasts in Sha'ban.

Hazrat Aisha (may Allah be pleased with her) narrates that during the blessed life of the Prophet (peace and blessings be upon him), I used to make up the missed fasts of Ramadan in the month of Sha'ban.

It is narrated from Hazrat Ubadah bin Samit that when the Messenger of Allah (peace and blessings be upon him) saw the moon, he would recite this supplication: Allah is the Greatest, Allah is the Greatest. The strength to avoid sin and the power to do good comes only from Allah. O Allah! I ask You for the goodness of this month, and I seek refuge with You from the evil of fate and from the calamity of the Day of Resurrection.

Hazrat Abdur Rahman bin Harmalah narrates that I came out of the mosque with Hazrat Saeed bin Musayyib. We said, "O Abu Muhammad! Look, the moon!" When he saw the moon, he said: "I believe in the Lord who created you, shaped you, and made your form balanced." Then he turned to me and said that the Holy Prophet (peace and blessings be upon him) used to say these words upon seeing the moon.

Hazrat Ali (may Allah be pleased with him) says that when any of you sees the moon, he should not raise his head; it is sufficient for you to say: "My Lord and your Lord is Allah."

Ibrahim says that when you see the moon, say: "My Lord and your Lord is Allah."
