Al-Matalib al-'Aliyah 2859 — The virtue of the words: There is none

It is narrated from Malik bin Qays (may Allah have mercy on him) that Sayyiduna Uqbah bin Amir (may Allah be pleased with him) came to Sayyiduna Mu'awiyah (may Allah be pleased with him) in Iliya (Bayt al-Maqdis). Only a little while had passed when he left from there; he was searched for but was not found. The narrator said: Then we reached him and saw that he was performing the prayer in an open, exposed stretch of ground. He asked: "For what purpose have you come here?" We said: "We have come to renew our meeting with you, or to fulfil your right of being visited." Sayyiduna Uqbah (may Allah be pleased with him) said: "I have your reward and gift for you: we were with the Messenger of Allah (peace and blessings be upon him)." Then he mentioned a hadith and said: "Then Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) said: 'O Ibn Amir, the Messenger of Allah (peace and blessings be upon him) said: Whoever bears witness that there is no god worthy of worship except Allah, in such a way that his heart fully confirms and supports his tongue, will enter Paradise by whichever of its gates he wishes.'"
Abu Ya'la recorded this hadith in his Musnad. Although Abd al-Rahman bin Ziyad bin An'um al-Ifriqi in its chain is da'if (weak) in terms of memory, this glad tiding of entering Paradise on the basis of Tawhid is established by other reliable and sahih hadith.
