Hadith: I have been intimidated in the path of Allah at a time when no one else was intimidated, and I have been harmed for the sake of Allah at a time when no one else was harmed, and I once spent thirty days and nights wherein I and Bilāl had nothing a living being can eat except a little that was kept under Bilāl's armpit

عن أنس، قال: قال رسول الله صلى الله عليه وسلم : «لقد أُخِفتُ في الله وما يُخافُ أحد، ولقد أُوذيت في الله وما يُؤذَى أحد، ولقد أَتَتْ عليَّ ثلاثون مِن بيْن يوم وليلة وما لي ولِبِلال طعامٌ يَأْكُلُه ذُو كَبِد إلا شيءٌ يُوارِيه إبطُ بلال».
[صحيح] - [رواه الترمذي وابن ماجه وأحمد]

Anas (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "I have been intimidated in the path of Allah at a time when no one else was intimidated, and I have been harmed for the sake of Allah at a time when no one else was harmed, and I once spent thirty days and nights wherein I and Bilāl had nothing a living being can eat except a little that was kept under Bilāl's armpit."
Sahih/Authentic. - [Ibn Maajah]

Explanation

In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) says that he was alone when he started proclaiming the message of Islam, and that the disbelievers intimidated him and harmed him because of that. At that time, he was alone with no support in the face of this harm other than the help, protection, and guidance of Allah, the Almighty. The Prophet (may Allah's peace and blessings be upon him) also says that he lacked money, food, and provisions at that phase to the extent that he once spent thirty days with no food but a little something that Bilāl (may Allah be pleased with him) used to carry under his armpit, because they did not even have a pot for keeping food. This Hadīth refers to the period when the Prophet (may Allah's peace and blessings be upon him) fled from Makkah.
