It is narrated from Sayyiduna Suhail bin Bayda that once people were on a journey with the Prophet (peace and blessings be upon him). I was sitting behind the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) called out loudly two or three times: "O Suhail bin Bayda!" Each time I replied, "Labbaik (I am here)." The people also heard this voice and thought that the Prophet (peace and blessings be upon him) wanted them to hear this as well. So those in front stopped at their places and those behind came closer. When all the people had gathered, the Prophet (peace and blessings be upon him) said: "Whoever bears witness that there is no god but Allah, Allah will make the fire of Hell forbidden for him and will make Paradise obligatory for him."
