The noble Quran:
The polytheists of the Quraysh gathered to consult each other on a strategy to prevent Prophet Muhammad, peace and blessings be upon him, from inviting people to Islam, especially as the Hajj (pilgrimage) season was nearing, and the Prophet , peace and blessings be upon him,would surely call people to embrace Islam during it. They agreed on warning people against listening to the Prophet , peace and blessings be upon him. Among the pilgrims was At-Tufayl ibn ‘Amr Ad-Dawsi, the chief of the tribe of Daws. The polytheists warned him about listening to the Prophet , peace and blessings be upon him, and claimed that he was a sorcerer and a poet, so At-Tufayl put pieces of cotton in his ears so that he would not be able to listen to the Prophet , peace and blessings be upon him.
Once, At-Tufayl went to the Ka‘bah and found the Prophet , peace and blessings be upon him, praying and reciting the Quran and Allaah The Almighty willed that At-Tufayl listened to him. When he listened, he knew that what he had listened to was neither poetry nor magic, as At-Tufayl was a poet himself. Thus, when the Prophet , peace and blessings be upon him, finished his prayer, At-Tufayl followed him home and told him what the polytheists had said. Then he asked the Prophet , peace and blessings be upon him, to explain Islam to him. When he heard the Da‘wah (call) of Islam, he believed in Allaah The Almighty, His Messenger and the Book he , peace and blessings be upon him,was sent with. The reversion of Tufayl was one of the blessings of the Quran. After this, he went to his tribe and invited them to Islam.
The noble Quran is the Speech of Allaah The Almighty and the eternal miracle of His Prophet Muhammad , peace and blessings be upon him,. Allaah The Almighty sent it down to the people of rhetoric and challenged them to compose one Soorah (Chapter) or even one verse like it, but they were unable to do so. The Quran is the firm Rope of Allaah The Almighty, and whoever adheres to it will be saved by it; whoever follows it will be guided to the right path.
The splitting of the moon:
Imaam Al-Bukhaari and Imaam Muslim, both, narrated that Abu Jahl, Al-Waleed ibn Al-Mugheerah, Al-‘Aas ibn Waa’il and a large number of the polytheists from the Quraysh went to the Prophet , peace and blessings be upon him, and said, “O Muhammad! If you are truthful in what you say, then split the moon for us into two pieces.” The Prophet , peace and blessings be upon him, invoked Allaah The Almighty to split the moon and Allaah The Almighty answered his invocation. The moon split and people saw it and the Prophet , peace and blessings be upon him, made them bear witness [to that], but they disbelieved. [Al-Bukhaari and Muslim]
Al-Israa’ and Al-Mi‘raaj (The Prophetic Journey and the Ascension):
When the polytheists intensified the harm they had inflicted on the Prophet , peace and blessings be upon him, Allaah The Almighty wanted to relieve his pains and bring him closer, so the journey of Al-Israa’ and Al-Mi‘raaj took place. Jibreel , may Allah be pleased with him, went to the Prophet , peace and blessings be upon him, with Al-Buraaq (a riding mount). The Prophet , peace and blessings be upon him, mounted it and he was taken from Al-Masjid Al-Haraam to Al-Masjid Al-Aqsa where he led all the Prophets in prayer, then he was taken to the upper heavens. During this journey, prayer was ordained, and the Prophet , peace and blessings be upon him, returned to Makkah on the same night.
Increasing small amounts of food:
During the Battle of the Trench, the polytheists besieged Madeenah, and the Prophet , peace and blessings be upon him, and his Companions may Allah be pleased with them were digging a trench around Al-Madeenah in order to prevent the polytheists from entering it. The Muslims ran out of food and they were starving. Jaabir wanted to provide the Prophet , peace and blessings be upon him, and his Companions with food, but he had a small amount of barley and a small sheep.
Thus, Jaabir went to the Prophet , peace and blessings be upon him, and invited him along with a small number of the Companions but the Prophet , peace and blessings be upon him, called out loudly: “O people! Jaabir has made food for you, so let us go!” The Prophet , peace and blessings be upon him, ordered Jaabir to wait for him before he prepared the food, and when he arrived there, he blessed the food. The Companions entered in groups until they all ate and the food remained the same. Jaabir said, “By Allaah! The fighters were one thousand on that day.” [Al-Bukhaari]
The trunk of a palm tree longs for the Prophet , peace and blessings be upon him:
The Prophet , peace and blessings be upon him, used to deliver his Khutbah (sermon) while standing beside the trunk of a date palm tree. When the Companions made a pulpit for him, he , peace and blessings be upon him, left the trunk and stood on the pulpit. The Companions heard a sound that was similar to the sound of a she-camel. The Prophet , peace and blessings be upon him, knew that it was the trunk weeping for having been separated from him. He went to it and placed his hand over it, so it calmed down. [Ahmad and At-Tirmithi]
