It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Recite this supplication: «اَللّٰهُمَّ إِنِّي أَسْأَلُكَ الْهُدَى وَالسَّدَادَ» 'O Allah! I ask You for guidance and steadfastness.' And when you say the word 'guidance,' keep in mind the guidance of the path, and when you say the word 'steadfastness,' keep in mind the straightness of the arrow." Sayyiduna Ali (may Allah be pleased with him) also said that the Prophet (peace and blessings be upon him) forbade (the use of) silk, red saddle cloth, and wearing a ring on the index or middle finger.
