How to Attain Complete Iman (Faith)   On the authority of Abu Huraira (may Allah be pleased with him)that Allah's Messenger (blessings and peace of Allah be upon him )said: " He who believes in Allah and the Last Day should speak well or keep silent ; and he who believes in Allah and the Last Day must honor his neighbor; and he who believes in Allah and the Last Day should treat his guest hospitably." Reported by al-Bukhari and Muslim                    Guidance and Moralities  This Hadith teaches us two of the most essential principles of Islam and its foundations:(1) 'Islam links all its acts charity and goodness to faith in Allah: (2) having good character and doing good to others are natural results of having good faith .' In the same vein, this Hadith states that al-Iman comprises all acts of a Muslim. Briefly, acts of al-Iman are of two kinds : 1)Those related to Allah's rights on human beings such as obligations (Salah,Sawm....)and giving up forbidden acts . 2) Those related to others' rights such as not harming them, being generous to guests, treating neighbors with kindness. Moreover,the Hadith implies that virtue of the tongue is among the best characteristics of al-Iman. The Beloved Prophet (blessings and peace of Allah be upon him )said : "One has no sound faith unless one has straight heart ;one has no straight heart unless one has straight tongue ." As for controlling one's tongue and speech, this Hadith urges Muslims to control their tongues, to think before speaking and speak only good. It is reported that one's speech should be for: 1-Remembrance of Allah . 2-Reading the Holy Qur'an . 3-Seeking information and asking for knowledge. 4-Speaking concerning some needed worldly matter. In addition, one has to join what is good and to forbid what is evil since he who keeps silent if there is some thing wrong, will be considered a dumb devil. This Hadith teaches that to refrain from doing bad acts is better than to do righteous deeds . In this Hadith, the Prophet (blessings and peace of Allah be upon him) sends us another message concerning neighbors. So, the Hadith orders every Muslim to treat his/her neighbor well.  The Prophet said: "By Allah, he is not a perfect Muslim. By Allah, his faith is incomplete. By Allah, he does not believe: the Prophet was asked 'O Messenger of Allah! Who is he?'The Prophet said: " One whose neighbor is not immune against his mischief." In Imam Muslim's narration: "That person will not enter paradise whose neighbor is not safe against his mischief." As you have seen, Islam gives neighborhood great respect, and even it makes treating neighbors well as an indication of one's complete faith. Islam sets a number of rules concerning this subject and grants neighbors many rights to be rendered. Among these rights are: - To help the neighbor if he asks for help . - To lend him money when in need. - To remove his deficiency. - To visit him when he is ill. - To congratulate him on happy occasions. - To offer him your condolences on unhappy occasions. - To escort the deceased neighbor to his final resting place. - To give him from your food as a present. - To raise not your building so as to prevent him air. - To know that " the best neighbor is one who behaves best towards his neighbors."  With regard to hospitality, this Hadith clearly and strongly orders us to be generous to guests if we are true believers. In the sound Hadith: "Anybody who believes in Allah and the Last Day should serve his guest generously by giving him his reward."It was asked: 'What is his reward, O Allah 's Messenger?'The Prophet said: "to be entertained generously for a day and a night with high quality food and the guest has the right to be entertained for three days." Finally,it is Islam ,only Islam ,that links behavior and faith ,religion and society in an unequaled way.
