Our Rasool (SAW) has said:
“Whosoever believes in Allah and in the Day of Judgment must treat his guest well, refrain from causing difficulties to his neighbor and whatever he utters must be good, or else he should hold his tongue.”
 
If a believer wants to have perfect faith, then he must practice upon these advises of our Nabi (SAW). In the narration of the Prophet (SAW), three important issues are mentioned:

1. Treating the guest well
2. Refraining from causing difficulty upon the neighbor
3. Speak good things or keep silent
   

In Islam, hosting the guest is a commendable virtue and holds great rewards. The believer should treat his guest with kindness and courtesy, speak politely to him, entertain him with food and drink and even accompany him to the door on his departure.
 
Someone once saw Hazrat Ali (RA) weeping and enquired about the cause of his weeping. He replied that seven days had passed without his having entertained a guest and he feared that maybe Allah had intended to dishonor him. Such is the status of entertaining the guest…. that the companions would become fearful when days passed and there did not appear any guest.
 
The second mentioned point is the treatment to one’s neighbors.
Many ahaadith have been narrated on this matter where our noble Prophet (SAW) spoke time and time again about the treatment to one’s neighbor.
Narrations such as:
“Treat your neighbor well.”…. and
“Be kind to your neighbor.”
 
Once the Prophet (SAW) was heard saying three times:
“By Allah he is not a believer… By Allah he is not a believer… By Allah he is not a believer.”
Someone asked who was such a person?
The Prophet (SAW) said:
“The person who causes suffering to his neighbor.”
In another hadith, he has said that such a person will not enter Jannah.
 
Allah revealed in Sura Nisa, verse 36:
“Worship Allah and do not attribute any partner to him, be kind and good to your parents, and to your kinsmen, orphans, the poor, near and distant neighbors, the companions at your sides and the wayfarers.”
 
Allah speaks about the near and distant neighbor.
The near neighbor can mean, the one nearest to you with respect to proximity or it can mean the neighbor who is Muslim even though he may live some houses away from you and it can also mean, the Muslim who is your relative.

Such a person who is a Muslim and a relative and lives in your locality has the most rights with respect to the rights of neighbors.
 
It was once reported to the Rasool (SAW) about a woman who was regular in her Tahajjud Salaat and fasting but was abusive to her neighbor. The Rasool (SAW) said: “She will enter Jahannam, though she might be taken out of it after undergoing her punishment.”

The Prophet (SAW) used to stress repeatedly regarding the rights of the neighbor.
He said:
“No one will ever understand these rights of the neighbor unless Allah has mercy on him.”
Let us observe the words of our Nabi (SAW) and pay our due rights to our neighbors, Inshaa Allah.
 
The third part of the hadith pertains to speaking good or else remaining silent. Allah (ST) says in Sura Nisa:
“People’s whispering and tale bearing are often devoid of goodness except those who encourage others to be charitable, virtuous or to have improved mutual relationships, and whosoever does this for the pleasure of Allah, We shall grant him immense rewards shortly.”
 
Once Abu Zar (RA) asked Rasool (SAW) for some advice. The Prophet (SAW) said to him:
“Observe silence most often, which will keep shaitaan away from you and help you in performing religious duties.”

The Prophet (SAW) used to frequently warn the believers about the improper use of the tongue. The tongue is such a creation of Allah, it is small in size yet it can perform one of the greatest deeds possible and that is professing to the belief in Allah. But on the other hand, that very same tongue can create severe sins which includes backbiting, slandering, obscene and abusive language, from amongst others.
 
So many mischiefs can be related to such a small thing as the tongue. The Prophet (SAW) has said that most of man’s sins arise because of the tongue.
Prophet Sulaiman (AS) was reported to have said: “If speech is silver, silence is gold.”
Luqman (AS) was renowned for his wisdom, so much so, Allah calls him Luqman, the Wise.
 
Luqman (AS) has said that Allah elevated him from a slave to one of a noble position because of four things:

1. Fear of Allah
2. Speaking the truth
3. Trustworthiness
4. And preferring silence to useless talk
   

The Rasool (SAW) said: “Restrain your tongue from uttering anything but good.”

Let us make effort to try to inculcate this hadith into our lives. The simple advises contained within it can change our entire lives.
