The Messenger of Allah said: "When the Iqamah is called for the prayer, do not come running. Come walking with tranquility. Whatever you catch up with, pray, and whatever you miss, complete it."
Sunan Ibn Majah Book 4, Hadith 41
← Previous Hadith "The Messenger of Allah said: 'When one of you performs ablution and does it well, then he comes to the mosque with no other motive but prayer and not seeking anything other than the prayer, he does not take one step but Allah raises him in status one degree thereby, and takes away one of his sins, until he enters the mosque. When he enters the mosque he is in a state of prayer so long as he is waiting for the prayer.'"

Sunan Ibn Majah Book 4, Hadith 40 Next Hadith → He heard the Messenger of Allah say: 'Shall I not tell you of something by means of which Allah expiates for sins and increases good deeds?' They said: 'Yes, O Messenger of Allah.' He said: 'Performing ablution properly despite difficulties, increasing the number of steps one takes towards the mosque and waiting for the next prayer after prayer.'
