“Jabir Ibn ‘Abdullah (may Allaah be pleased with him )said, “ The Messenger of Allaah (peace and blessings be upon him) supplicated to Allaah in this masjid (Masjid Al-Fath) on Monday, Tuesday and Wednesday. His dua was answered on Wednesday between the prayers of Thur and Asr. Jabir(may Allaah be pleased with him)said,” There wasn’t anything that was crucially important for me to have solved, except I called on Allaah during that hour of the day between Thur and Asr knowing He would answer.”
Graded Hasan by Shaykh Al-Albani(May Allaah have mercy upon him) in Saheeh Adab Al-Mufrad.
Shaykh Hussain Awayaasha(may Allaah preserve him )said in his explanation of Saheeh Adab Al-Mufrad.
“The Messenger of Allaah (peace and blessings be upon him)supplicated to Allaah in this masjid(Masjid Al-Fath )on Monday, Tuesday and Wednesday” Masjid Al-Fath: is a masjid located on the eastside at the top of a mountain stump. A person can ascend to this masjid by two routes; one on the east and the
other on the north side. This is the general meaning of Masjid al-Fath. It has also been said that Masjid Al-Fath is Masjid Ahzab or a Masjid on High ground. [ Fadl 2/174]
“His dua was answered on Wednesday between the prayers of Thur and Asr” . Shaykh Al-Albani(may Allaah shower him with mercy) commented on this saying: If this companion wouldn’t have narrated to us that the prophet(peace and blessings be upon him)made Dua to Allaah during this hour we wouldn’t have known. The person present witnesses what the absent person doesn’t. This hadeeth has significant meaning;since Jabir narrated the information when exactly his dua was answered. And this shows that the Dua for the Messenger(peace and blessings be upon him)was answered at that hour during Wednesday. Consequently Jabir began to do that same thing he saw Muhammad (peace and blessings be upon him) do on Wednesday between Thur and Asr. End of Quote from the book.
Ibn Taymeeyah (728H) said in his book “ Iqtedahus Siratul Mustaqeem (1/433), ” A group of our companions and other people act by this hadeeth. They see to it that they call on Allaah during this time; as narrated by Jabir(may Allaah be pleased with him). The place where Jabir made Dua to Allaah isn’t mentioned, but the time period in which he did is mentioned.
