Fasting Rajab and what has come about it

Kharashah bin al-Hurr says: I saw Sayyiduna Umar (may Allah be pleased with him) striking people's hands in Rajab until they put their hands into the dishes to eat. He would say: "Eat, for this is a month that the people of the Jahiliyyah (pre-Islamic ignorance) used to venerate."

Zayd bin Aslam says that the Messenger of Allah (peace and blessings be upon him) was asked about fasting in Rajab, and he said: "Why do you not fast in Sha'ban?"

Sayyiduna Anas (may Allah be pleased with him) says: Do not make it your habit to fast on Mondays, on Thursdays, or in Rajab.

When Sayyiduna Ibn Umar (may Allah be pleased with them both) saw people making arrangements for fasting in Rajab, he would consider it disliked.
