Allah's Messenger (ﷺ) forbade Al-Wisal (fasting continuously for more than one day without taking any
meals). A man from the Muslims said, "But you do Al-Wisal, O Allah's Messenger (ﷺ)!" Allah's Messenger (ﷺ) I
said, "Who among you is similar to me? I sleep and my Lord makes me eat and drink." When the
people refused to give up Al-Wisal, the Prophet (ﷺ) fasted along with them for one day, and did not break
his fast but continued his fast for another day, and when they saw the crescent, the Prophet (ﷺ) said, "If
the crescent had not appeared, I would have made you continue your fast (for a third day)," as if he
wanted to punish them for they had refused to give up Al-Wisal.
Sahih al-Bukhari Book 86, Hadith 73
"When the Prophet (ﷺ) started to pray, he would say the takbir, then say: 'Inna salati wa nusuki wa mahyaya wa mamati lillahi rabbil-alamin, la sharika lahu, wa bidhalika umirtu wa ana min al-muslimin. Allahummahdini liahsanil-amali wa ahsanil-akhlaqi la yahdi li ahsaniha illa anta wa qini sayy'al-a'mali wa sayy'al-ahaqi la yaqi sayy'aha illa ant. (Indeed my salah (prayer), my sacrifice, my living, and my dying are for Allah, the Lord of all that exists. He has no partner. And of this I have been commanded, and I am one of the Muslims. O Allah, guide me to the best of deeds and the best of manners, for none can guide to the best of them but You. And protect me from bad deeds and bad manners, for none can protect against them but You.) "
