Within the directives of Sayed. Al-Sistani to the visitors of Imam Al-Hussayn (peace be upon him): Fear Allah in devotion..

Among the recommendations and directives issued by the office of the Supreme Religious Authority Sayed. Ali Al-Hussayni Al-Sistani for the visitors travelling to perform the Ziyarat Arba'een of Imam Al-Hussayn (peace be upon him), stressing on the importance of the sincerity and devotion as follows:
Fear Allah in devotion inasmuch as the value and blessings of one's deeds depends on how far he is devoted in performing them for Allah's sake. Because Allah will not accept any deeds which are not purely for Him. It has been narrated from the Holy Prophet (Prayers and Allah's peace be upon him and his holy Household) that he said during Muslims' emigration from Mecca to Medina: "Whoever migrates for the sake of Allah and His Messenger, he has migrated to Him and whoever migrates to make worldly gains, he has migrated to the world. Allah will reward devoted deeds to the extent that it will increase to seven hundred folds and He doubles the rewards for whomsoever He wants."
Hence, it is necessary on the visitors (pilgrims) to remember Allah and recite Dhikr of Allah and be mindful of every step and every deed to be for Allah's sake. They should know that Allah has not bestowed anyone with a blessing so precious as sincerity and devotion in belief, sayings and conducts. An act which is devoid of sincerity and devotion ends with the end of life in this world whereas a since act will be lasting and blessed in this world and the hereafter.
