A Mareed is a person who is sick or unwell. Islam provides numerous concessions (Rukhsah) for the Mareed to ensure that religious obligations do not cause them harm. For instance, a sick person is permitted to sit or lie down during prayer, to break their fast in Ramadan, or to perform Tayammum instead of Wudu if water would worsen their condition. Visiting the Mareed (Iyadat al-Marid) is a highly rewarded communal duty, as it provides emotional support and strengthens the bonds of mercy within the society, reflecting the Prophet's deep concern for the vulnerable. The concessions for the sick are based on the Quran: "Allah does not burden a soul beyond its capacity" (2:286). The Prophet (peace be upon him) said: "When a servant falls ill, Allah says: 'Record for him the deeds he used to do when he was healthy'" (Ahmad). This is a mercy, as the sick person continues to receive reward for their good intentions. For prayer, a sick person may pray sitting if they cannot stand. If they cannot sit, they may pray lying down, gesturing with their head for the bowing and prostration. If they cannot gesture, they may pray with their eyes. The prayer is not waived; it is adapted to the person's capacity. For fasting, a sick person may break their fast if fasting would harm them. They must make up the missed days later. If the illness is chronic and they cannot fast permanently, they pay fidya (feeding a poor person for each missed day). For purification, if a sick person cannot use water without harm, they perform tayammum (dry ablution) with clean earth. Visiting the sick (iyadat al-marid) is a sunnah with great reward. The Prophet said: "Whoever visits a sick person, a caller from heaven calls: 'May you be blessed, and may your walking be blessed, and may you take a place in Paradise'" (Tirmidhi). For believers, the rules for the mareed are a reminder of Allah's mercy. He does not burden a soul beyond its capacity. When sickness makes worship difficult, He provides ease. The believer takes advantage of these concessions, not as a license to neglect worship, but as a way to maintain worship in a manner suited to their circumstances. Visiting the sick is also a way to earn reward and to strengthen community bonds. The believer visits those who are ill, offering comfort, making du'a for their recovery, and showing the mercy that the Prophet taught. The ultimate healing is from Allah. The believer seeks medical treatment, makes du'a, and trusts in Allah, the Healer (ash-Shafi). They know that sickness can be a means of expiating sins and elevating ranks, and they accept Allah's decree with patience and hope.
